\fB/usr/local/etc/smartd.conf\fP is the configuration file for the \fBsmartd\fP

36
If the configuration file \fB/usr/local/etc/smartd.conf\fP is present,
37
\fBsmartd\fP reads it at startup, before \fBfork\fP(2)ing into the
38
background. If \fBsmartd\fP subsequently receives a \fBHUP\fP signal,
39
it will then re-read the configuration file. If \fBsmartd\fP is
40
running in debug mode, then an \fBINT\fP signal will also make it
41
re-read the configuration file. This signal can be generated by typing

76
This can be annoying if you have an ATA or SCSI device that hangs or

distribution. You will find this sample configuration file in
91
\fB/usr/local/share/doc/smartmontools-5.1/\fP. For security, the configuration file

There should be one device listed per line, although you may have

.SH CONFIGURATION FILE DIRECTIVES
237
If a non-comment entry in the configuration file is the text string
239
in capital letters, then
241
will ignore any remaining lines in the configuration file, and will
244
may optionally be followed by Directives that will apply to all
245
devices that are found in the scan. Please see below for additional
249
The following are the Directives that may appear following the device
253
.B /usr/local/etc/smartd.conf
254
configuration file. Note that
255
.B these are NOT command-line options for
257
The Directives below may appear in any order, following the device
260
.B For an ATA device,
261
if no Directives appear, then the device will be monitored
262
as if the \'\-a\' Directive (monitor all SMART properties) had been given.
264
.B If a SCSI disk is listed,
265
it will be monitored at the maximum implemented level: roughly
266
equivalent to using the \'\-H \-l selftest\' options for an ATA disk.
267
So with the exception of \'\-d\', \'\-m\', \'\-l selftest\', \'\-s\', and
268
\'\-M\', the Directives below are ignored for SCSI disks. For SCSI
269
disks, the \'\-m\' Directive sends a warning email if the SMART status
270
indicates a disk failure or problem, if the SCSI inquiry about disk
271
status fails, or if new errors appear in the self-test log.
273
.B If a 3ware controller is used
274
then the corresponding SCSI (/dev/sd?) or character device (/dev/twe?
275
or /dev/twa?) must be listed, along with the \'\-d 3ware,N\' Directive
276
(see below). The individual ATA disks hosted by the 3ware controller
277
appear to \fBsmartd\fP as normal ATA devices. Hence all the ATA
278
directives can be used for these disks (but see note below).
280
.B If an Areca controller is used
281
then the corresponding SCSI generic device (/dev/sg?) must be listed,
282
along with the \'\-d areca,N\' Directive (see below). The individual
283
SATA disks hosted by the Areca controller appear to \fBsmartd\fP as
284
normal ATA devices. Hence all the ATA directives can be used for
285
these disks. Areca firmware version 1.46 or later which supports
286
smartmontools must be used; Please see the \fBsmartctl\fP(8) man page
291
Specifies the type of the device. This Directive may be used multiple
292
times for one device, but the arguments \fIata\fP, \fIscsi\fP,
293
\fIsat\fP, \fImarvell\fP, \fIcciss,N\fP, \fIareca,N\fP, \fImegaraid,N\fP
294
and \fI3ware,N\fP are mutually-exclusive. If more than one is given then
295
\fBsmartd\fP will use the last one which appears.
297
If none of these three arguments is given, then \fBsmartd\fP will
298
first attempt to guess the device type by looking at whether the sixth
299
character in the device name is an \'s\' or an \'h\'. This will work for
300
device names like /dev/hda or /dev/sdb, and corresponds to choosing
301
\fIata\fP or \fIscsi\fP respectively. If
303
can\'t guess from this sixth character, then it will simply try to
304
access the device using first ATA and then SCSI ioctl()s.
306
The valid arguments to this Directive are:
309
\- the device type is ATA. This prevents
311
from issuing SCSI commands to an ATA device.
314
\- the device type is SCSI. This prevents
316
from issuing ATA commands to a SCSI device.
319
\- the device type is SCSI to ATA Translation (SAT).
321
will generate ATA (smart) commands and then package them in
322
the SAT defined ATA PASS THROUGH SCSI commands. The commands
323
are then routed through the SCSI pass through interface to the
324
operating system. There are two types of ATA PASS THROUGH
325
SCSI commands: a 12 byte and 16 byte variant.
327
can use either and defaults to the 16 byte variant. This can
328
be overridden with this syntax: \'\-d sat,12\' or \'\-d sat,16\'.
331
\- Under Linux, interact with SATA disks behind Marvell chip-set
332
controllers (using the Marvell rather than libata driver).
335
\- the device consists of one or more SCSI/SAS/SATA disks connected
336
to a MegaRAID controller. The non-negative integer N (in the range
337
of 0 to 127 inclusive) denotes which disk on the controller is monitored.
338
In log files and email messages this disk will be identified as
339
megaraid_disk_XXX with XXX in the range from 000 to 127 inclusive.
342
\- the device consists of one or more ATA disks connected to a 3ware
343
RAID controller. The non-negative integer N (in the range from 0 to 127
344
inclusive) denotes which disk on the controller is monitored. In log
345
files and email messages this disk will be identified as 3ware_disk_XXX
346
with XXX in the range from 000 to 127 inclusive.
348
This Directive may at first appear confusing, because the 3ware
349
controller is a SCSI device (such as /dev/sda) and should be listed as
350
such in the the configuration file.
351
However when the \'\-d 3ware,N\'
352
Directive is used, then the corresponding disk is addressed using
353
native ATA commands which are \'passed through\' the SCSI driver. All
354
ATA Directives listed in this man page may be used. Note that while
355
you may use \fBany\fP of the 3ware SCSI logical devices /dev/sd? to
356
address \fBany\fP of the physical disks (3ware ports), error and log
357
messages will make the most sense if you always list the 3ware SCSI
358
logical device corresponding to the particular physical disks. Please
359
see the \fBsmartctl\fP(8) man page for further details.
361
ATA disks behind 3ware controllers may alternatively be accessed via a
362
character device interface /dev/twe0-15 (3ware 6000/7000/8000
363
controllers) and /dev/twa0-15 (3ware 9000 series controllers). Note
364
that the 9000 series controllers may \fBonly\fP be accessed using the
365
character device interface /dev/twa0-15 and not the SCSI device
366
interface /dev/sd?. Please see the \fBsmartctl\fP(8) man page for
369
Note that older 3w-xxxx drivers do not pass the \'Enable Autosave\'
370
(\fB-S on\fP) and \'Enable Automatic Offline\' (\fB-o on\fP) commands
371
to the disk, if the SCSI interface is used, and produce these types of
372
harmless syslog error messages instead: \fB\'3w-xxxx: tw_ioctl():
373
Passthru size (123392) too big\'\fP. This can be fixed by upgrading to
374
version 1.02.00.037 or later of the 3w-xxxx driver, or by applying a
375
patch to older versions. See
376
\fBhttp://smartmontools.sourceforge.net/\fP for instructions.
377
Alternatively use the character device interfaces /dev/twe0-15 (3ware
378
6/7/8000 series controllers) or /dev/twa0-15 (3ware 9000 series
382
\- the device consists of one or more SATA disks connected to an Areca
383
SATA RAID controller. The positive integer N (in the range from 1 to
384
24 inclusive) denotes which disk on the controller is monitored. In
385
log files and email messages this disk will be identifed as
386
areca_disk_XX with XX in the range from 01 to 24 inclusive.
389
\- the device consists of one or more SCSI disks connected to a cciss
390
RAID controller. The non-negative integer N (in the range from 0 to 15
391
inclusive) denotes which disk on the controller is monitored. In log
392
files and email messages this disk will be identified as cciss_disk_XX
393
with XX in the range from 00 to 15 inclusive.
395
.B 3ware, MegaRAID, Areca and cciss controllers are currently ONLY supported under Linux.
398
\- the device consists of one or more ATA disks connected to a HighPoint
399
RocketRAID controller. The integer L is the controller id, the integer M
400
is the channel number, and the integer N is the PMPort number if it is
401
available. The allowed values of L are from 1 to 4 inclusive, M are from
402
1 to 8 inclusive and N from 1 to 4 if PMPort available. And also these
403
values are limited by the model of the HighPoint RocketRAID controller.
404
In log files and email messages this disk will be identified as
405
hpt_X/X/X and X/X/X is the same as L/M/N, note if no N indicated, N set
406
to the default value 1.
408
.B HighPoint RocketRAID controllers are currently ONLY supported under Linux and FreeBSD.
411
\- the device or its media is removable. This indicates to
413
that it should continue (instead of exiting, which is the default
414
behavior) if the device does not appear to be present when
415
\fBsmartd\fP is started. This Directive may be used in conjunction
416
with the other \'\-d\' Directives.
419
.B \-n POWERMODE[,N][,q]
420
This \'nocheck\' Directive is used to prevent a disk from being
421
spun-up when it is periodically polled by \fBsmartd\fP.
423
ATA disks have five different power states. In order of increasing
424
power consumption they are: \'OFF\', \'SLEEP\', \'STANDBY\', \'IDLE\',
425
and \'ACTIVE\'. Typically in the OFF, SLEEP, and STANDBY modes the
426
disk\'s platters are not spinning. But usually, in response to SMART
427
commands issued by \fBsmartd\fP, the disk platters are spun up. So if
428
this option is not used, then a disk which is in a low\-power mode may
429
be spun up and put into a higher\-power mode when it is periodically
430
polled by \fBsmartd\fP.
432
Note that if the disk is in SLEEP mode when \fBsmartd\fP is started,
433
then it won't respond to \fBsmartd\fP commands, and so the disk won't
434
be registered as a device for \fBsmartd\fP to monitor. If a disk is in
435
any other low\-power mode, then the commands issued by \fBsmartd\fP to
436
register the disk will probably cause it to spin\-up.
438
The \'\fB\-n\fP\' (nocheck) Directive specifies if \fBsmartd\fP\'s
439
periodic checks should still be carried out when the device is in a
440
low\-power mode. It may be used to prevent a disk from being spun\-up
441
by periodic \fBsmartd\fP polling. The allowed values of POWERMODE
445
\- \fBsmartd\fP will poll (check) the device regardless of its power
446
mode. This may cause a disk which is spun\-down to be spun\-up when
447
\fBsmartd\fP checks it. This is the default behavior if the '\-n'
448
Directive is not given.
451
\- check the device unless it is in SLEEP mode.
454
\- check the device unless it is in SLEEP or STANDBY mode. In
455
these modes most disks are not spinning, so if you want to prevent
456
a laptop disk from spinning up each time that \fBsmartd\fP polls,
457
this is probably what you want.
460
\- check the device unless it is in SLEEP, STANDBY or IDLE mode.
461
In the IDLE state, most disks are still spinning, so this is probably
464
Maximum number of skipped checks (in a row) can be specified by
465
appending positive number \',N\' to POWERMODE (like \'\-n standby,15\').
466
After N checks are skipped in a row, powermode is ignored and the
467
check is performed anyway.
469
When a periodic test is skipped, \fBsmartd\fP normally writes an
470
informal log message. The message can be suppressed by appending
471
the option \',q\' to POWERMODE (like \'\-n standby,q\').
472
This prevents a laptop disk from spinning up due to this message.
474
Both \',N\' and \',q\' can be specified together.
478
Specifies how tolerant
480
should be of SMART command failures. The valid arguments to this
484
\- do not try to monitor the disk if a mandatory SMART command fails, but
485
continue if an optional SMART command fails. This is the default.
488
\- try to monitor the disk even if it appears to lack SMART
489
capabilities. This may be required for some old disks (prior to
490
ATA\-3 revision 4) that implemented SMART before the SMART standards
491
were incorporated into the ATA/ATAPI Specifications. This may also be
492
needed for some Maxtor disks which fail to comply with the ATA
493
Specifications and don't properly indicate support for error\- or
496
[Please see the \fBsmartctl \-T\fP command-line option.]
499
Enables or disables SMART Automatic Offline Testing when
501
starts up and has no further effect. The valid arguments to this
502
Directive are \fIon\fP and \fIoff\fP.
504
The delay between tests is vendor-specific, but is typically four
507
Note that SMART Automatic Offline Testing is \fBnot\fP part of the ATA
508
Specification. Please see the
510
command-line option documentation for further information about this
514
Enables or disables Attribute Autosave when \fBsmartd\fP
515
starts up and has no further effect. The valid arguments to this
516
Directive are \fIon\fP and \fIoff\fP. Also affects SCSI devices.
517
[Please see the \fBsmartctl \-S\fP command-line option.]
520
Check the SMART health status of the disk. If any Prefailure

Reports increases in the number of errors in one of the two SMART logs. The
530
valid arguments to this Directive are:
533
\- report if the number of ATA errors reported in the ATA Error Log
534
has increased since the last check.
537
\- report if the number of failed tests reported in the SMART
538
Self-Test Log has increased since the last check, or if the timestamp
539
associated with the most recent failed test has increased. Note that
540
such errors will \fBonly\fP be logged if you run self-tests on the
541
disk (and it fails a test!). Self-Tests can be run automatically by

To setup a full test of a 1TB disk within 20 days (one 50GB span
621
each day), run this command once:
623
smartctl -t select,0-99999999 /dev/sda
625
To run the next test spans on Monday-Friday between 12-13am, run smartd
628
\fB \-s n/../../[1-5]/12\fP
632
Scheduled tests are run immediately following the regularly-scheduled
633
device polling, if the current local date, time, and test type, match
634
\fBREGEXP\fP. By default the regularly-scheduled device polling
635
occurs every thirty minutes after starting \fBsmartd\fP. Take caution
636
if you use the \'\-i\' option to make this polling interval more than
637
sixty minutes: the poll times may fail to coincide with any of the
638
testing times that you have specified with \fBREGEXP\fP. In this case
639
the test will be run following the next device polling.
641
Before running an offline or self-test, \fBsmartd\fP checks to be sure
642
that a self-test is not already running. If a self-test \fBis\fP
643
already running, then this running self test will \fBnot\fP be
644
interrupted to begin another test.
646
\fBsmartd\fP will not attempt to run \fBany\fP type of test if another
647
test was already started or run in the same hour.
649
To avoid performance problems during system boot, \fBsmartd\fP will
650
not attempt to run any scheduled tests following the very first
651
device polling (unless \'\-q onecheck\' is specified).
653
Each time a test is run, \fBsmartd\fP will log an entry to SYSLOG.
654
You can use these or the '-q showtests' command-line option to verify
655
that you constructed \fBREGEXP\fP correctly. The matching order
656
(\fBL\fP before \fBS\fP before \fBC\fP before \fBO\fP) ensures that
657
if multiple test types are all scheduled for the same hour, the
658
longer test type has precedence. This is usually the desired behavior.
660
If the scheduled tests are used in conjunction with state persistence
661
(\'\-s\' option), smartd will also try to match the hours since last
662
shutdown (or 90 days at most). If any test would have been started
663
during downtime, the longest (see above) of these tests is run after
664
second device polling.
666
If the \'\-n\' directive is used and any test would have been started
667
during disk standby time, the longest of these tests is run when the
668
disk is active again.
670
Unix users: please beware that the rules for extended regular
671
expressions [regex(7)] are \fBnot\fP the same as the rules for
672
file\-name pattern matching by the shell [glob(7)]. \fBsmartd\fP will
673
issue harmless informational warning messages if it detects characters
674
in \fBREGEXP\fP that appear to indicate that you have made this
679
Send a warning email to the email address \fBADD\fP if the \'\-H\',
680
\'\-l\', \'\-f\', \'\-C\', or \'\-O\' Directives detect a failure or a
681
new error, or if a SMART command to the disk fails. This Directive
682
only works in conjunction with these other Directives (or with the
683
equivalent default \'\-a\' Directive).
685
To prevent your email in-box from getting filled up with warning
686
messages, by default only a single warning will be sent for each of
687
the enabled alert types, \'\-H\', \'\-l\', \'\-f\', \'\-C\', or
688
\'\-O\' even if more than one failure or error is detected or if the
689
failure or error persists. [This behavior can be modified; see the
690
\'\-M\' Directive below.]
692
To send email to more than one user, please use the following "comma
693
separated" form for the address: \fBuser1@add1,user2@add2,...,userN@addN\fP
696
To test that email is being sent correctly, use the \'\-M test\'
697
Directive described below to send one test email message on
701
By default, email is sent using the system
703
command. In order that
705
find the mail command (normally /bin/mail) an executable named
707
must be in the path of the shell or environment from which
709
was started. If you wish to specify an explicit path to the mail
710
executable (for example /usr/local/bin/mail) or a custom script to
711
run, please use the \'\-M exec\' Directive below.
713
Note that by default under Solaris, in the previous paragraph,
714
\'\fBmailx\fP\' and \'\fB/bin/mailx\fP\' are used, since Solaris
715
\'/bin/mail\' does not accept a \'\-s\' (Subject) command-line
718
On Windows, the \'\fBBlat\fP\' mailer
719
(\fBhttp://blat.sourceforge.net/\fP) is used by default.
720
This mailer uses a different command line syntax, see
723
Note also that there is a special argument
725
which can be given to the \'\-m\' Directive in conjunction with the \'\-M
726
exec\' Directive. Please see below for an explanation of its effect.
728
If the mailer or the shell running it produces any STDERR/STDOUT
729
output, then a snippet of that output will be copied to SYSLOG. The
730
remainder of the output is discarded. If problems are encountered in
731
sending mail, this should help you to understand and fix them. If
732
you have mail problems, we recommend running \fBsmartd\fP in debug
733
mode with the \'-d\' flag, using the \'-M test\' Directive described
736
The following extension is available on Windows:
737
By specifying \'\fBmsgbox\fP\' as a mail address, a warning
738
"email" is displayed as a message box on the screen.
739
Using both \'\fBmsgbox\fP\' and regular mail addresses is possible,
740
if \'\fBmsgbox\fP\' is the first word in the comma separated list.
741
With \'\fBsysmsgbox\fP\', a system modal (always on top) message box
742
is used. If running as a service, a service notification message box
743
(always shown on current visible desktop) is used.
747
These Directives modify the behavior of the
749
email warnings enabled with the \'\-m\' email Directive described above.
750
These \'\-M\' Directives only work in conjunction with the \'\-m\'
751
Directive and can not be used without it.
753
Multiple \-M Directives may be given. If more than one of the
754
following three \-M Directives are given (example: \-M once \-M daily)
755
then the final one (in the example, \-M daily) is used.
757
The valid arguments to the \-M Directive are (one of the following
761
\- send only one warning email for each type of disk problem detected. This
765
\- send additional warning reminder emails, once per day, for each type
766
of disk problem detected.
769
\- send additional warning reminder emails, after a one-day interval,
770
then a two-day interval, then a four-day interval, and so on for each
771
type of disk problem detected. Each interval is twice as long as the
774
In addition, one may add zero or more of the following Directives:
777
\- send a single test email
780
startup. This allows one to verify that email is delivered correctly.
781
Note that if this Directive is used,
783
will also send the normal email warnings that were enabled with the \'\-m\' Directive,
784
in addition to the single test email!
787
\- run the executable PATH instead of the default mail command, when
789
needs to send email. PATH must point to an executable binary file or
792
By setting PATH to point to a customized script, you can make
793
\fBsmartd\fP perform useful tricks when a disk problem is detected
794
(beeping the console, shutting down the machine, broadcasting warnings
795
to all logged-in users, etc.) But please be careful. \fBsmartd\fP
796
will \fBblock\fP until the executable PATH returns, so if your
797
executable hangs, then \fBsmartd\fP will also hang. Some sample
798
scripts are included in
799
/usr/local/share/doc/smartmontools-5.1/examplescripts/.
801
The return status of the executable is recorded by \fBsmartd\fP in
802
SYSLOG. The executable is not expected to write to STDOUT or
803
STDERR. If it does, then this is interpreted as indicating that
804
something is going wrong with your executable, and a fragment of this
805
output is logged to SYSLOG to help you to understand the problem.
806
Normally, if you wish to leave some record behind, the executable
807
should send mail or write to a file or device.
809
Before running the executable, \fBsmartd\fP sets a number of
810
environment variables. These environment variables may be used to
811
control the executable\'s behavior. The environment variables
812
exported by \fBsmartd\fP are:
814
.IP \fBSMARTD_MAILER\fP 4
815
is set to the argument of \-M exec, if present or else to \'mail\'
816
(examples: /bin/mail, mail).
817
.IP \fBSMARTD_DEVICE\fP 4
818
is set to the device path (examples: /dev/hda, /dev/sdb).
819
.IP \fBSMARTD_DEVICETYPE\fP 4
820
is set to the device type (possible values: ata, scsi, 3ware,N,
821
areca,N, hpt,L/M/N). Here N=0,...,127 denotes the ATA disk behind a
822
3ware RAID controller and L/M/N denotes the SATA disk behind a
823
HighPoint RocketRAID controller.
824
.IP \fBSMARTD_DEVICESTRING\fP 4
825
is set to the device description. For SMARTD_DEVICETYPE of ata or
826
scsi, this is the same as SMARTD_DEVICE. For 3ware RAID controllers,
827
the form used is \'/dev/sdc [3ware_disk_01]\'. For HighPoint
828
RocketRAID controller, the form is \'/dev/sdd [hpt_1/1/1]\' under Linux
829
or \'/dev/hptrr [hpt_1/1/1]\' under FreeBSD. For Areca controllers, the
830
form is \'/dev/sg2 [areca_disk_09]\'. In these cases the device string
831
contains a space and is NOT quoted. So to use $SMARTD_DEVICESTRING in a
832
bash script you should probably enclose it in double quotes.
833
.IP \fBSMARTD_FAILTYPE\fP 4
834
gives the reason for the warning or message email. The possible values that
835
it takes and their meanings are:
838
\fIEmailTest\fP: this is an email test message.
841
\fIHealth\fP: the SMART health status indicates imminent failure.
844
\fIUsage\fP: a usage Attribute has failed.
847
\fISelfTest\fP: the number of self-test failures has increased.
850
\fIErrorCount\fP: the number of errors in the ATA error log has increased.
853
\fICurrentPendingSector\fP: one of more disk sectors could not be
854
read and are marked to be reallocated (replaced with spare sectors).
857
\fIOfflineUncorrectableSector\fP: during off\-line testing, or self\-testing,
858
one or more disk sectors could not be read.
861
\fIFailedHealthCheck\fP: the SMART health status command failed.
864
\fIFailedReadSmartData\fP: the command to read SMART Attribute data failed.
867
\fIFailedReadSmartErrorLog\fP: the command to read the SMART error log failed.
870
\fIFailedReadSmartSelfTestLog\fP: the command to read the SMART self-test log failed.
873
\fIFailedOpenDevice\fP: the open() command to the device failed.
874
.IP \fBSMARTD_ADDRESS\fP 4
875
is determined by the address argument ADD of the \'\-m\' Directive.
876
If ADD is \fB<nomailer>\fP, then \fBSMARTD_ADDRESS\fP is not set.
877
Otherwise, it is set to the comma-separated-list of email addresses
878
given by the argument ADD, with the commas replaced by spaces
879
(example:admin@example.com root). If more than one email address is
880
given, then this string will contain space characters and is NOT
881
quoted, so to use it in a bash script you may want to enclose it in
883
.IP \fBSMARTD_MESSAGE\fP 4
884
is set to the one sentence summary warning email message string from
886
This message string contains space characters and is NOT quoted. So to
887
use $SMARTD_MESSAGE in a bash script you should probably enclose it in
889
.IP \fBSMARTD_FULLMESSAGE\fP 4
890
is set to the contents of the entire email warning message string from
892
This message string contains space and return characters and is NOT quoted. So to
893
use $SMARTD_FULLMESSAGE in a bash script you should probably enclose it in
895
.IP \fBSMARTD_TFIRST\fP 4
896
is a text string giving the time and date at which the first problem
897
of this type was reported. This text string contains space characters
898
and no newlines, and is NOT quoted. For example:
901
Sun Feb 9 14:58:19 2003 CST
902
.IP \fBSMARTD_TFIRSTEPOCH\fP 4
903
is an integer, which is the unix epoch (number of seconds since Jan 1,
904
1970) for \fBSMARTD_TFIRST\fP.
906
.\" The following two lines are a workaround for a man2html bug. Please leave them.
907
.\" They define a non-existent option; useful because man2html can't correctly reset the margins.
910
The shell which is used to run PATH is system-dependent. For vanilla
911
Linux/glibc it\'s bash. For other systems, the man page for
912
\fBpopen\fP(3) should say what shell is used.
914
If the \'\-m ADD\' Directive is given with a normal address argument,
915
then the executable pointed to by PATH will be run in a shell with
916
STDIN receiving the body of the email message, and with the same
917
command-line arguments:
919
-s "$SMARTD_SUBJECT" $SMARTD_ADDRESS
921
that would normally be provided to \'mail\'. Examples include:
923
.B -m user@home -M exec /bin/mail
924
.B -m admin@work -M exec /usr/local/bin/mailto
925
.B -m root -M exec /Example_1/bash/script/below
928
Note that on Windows, the syntax of the \'\fBBlat\fP\' mailer is
931
- -q -subject "$SMARTD_SUBJECT" -to "$SMARTD_ADDRESS"
934
If the \'\-m ADD\' Directive is given with the special address argument
936
then the executable pointed to by PATH is run in a shell with
940
command-line arguments, for example:
942
.B -m <nomailer> -M exec /Example_2/bash/script/below
944
If the executable produces any STDERR/STDOUT output, then \fBsmartd\fP
945
assumes that something is going wrong, and a snippet of that output
946
will be copied to SYSLOG. The remainder of the output is then
949
Some EXAMPLES of scripts that can be used with the \'\-M exec\'
950
Directive are given below. Some sample scripts are also included in
951
/usr/local/share/doc/smartmontools-5.1/examplescripts/.
955
Check for \'failure\' of any Usage Attributes. If these Attributes are
956
less than or equal to the threshold, it does NOT indicate imminent
957
disk failure. It "indicates an advisory condition where the usage or
958
age of the device has exceeded its intended design life period."
959
[Please see the \fBsmartctl \-A\fP command-line option.]
962
Report anytime that a Prefail Attribute has changed
963
its value since the last check, 30 minutes ago. [Please see the
965
command-line option.]
968
Report anytime that a Usage Attribute has changed its value
969
since the last check, 30 minutes ago. [Please see the
971
command-line option.]
974
Equivalent to turning on the two previous flags \'\-p\' and \'\-u\'.
975
Tracks changes in \fIall\fP device Attributes (both Prefailure and
976
Usage). [Please see the \fBsmartctl\fP \-A command-line option.]
979
Ignore device Attribute number \fBID\fP when checking for failure of
980
Usage Attributes. \fBID\fP must be a decimal integer in the range
981
from 1 to 255. This Directive modifies the behavior of the \'\-f\'
982
Directive and has no effect without it.
984
This is useful, for example, if you have a very old disk and don\'t
985
want to keep getting messages about the hours-on-lifetime Attribute
986
(usually Attribute 9) failing. This Directive may appear multiple
987
times for a single device, if you want to ignore multiple Attributes.
990
Ignore device Attribute \fBID\fP when tracking changes in the
991
Attribute values. \fBID\fP must be a decimal integer in the range
992
from 1 to 255. This Directive modifies the behavior of the \'\-p\',
993
\'\-u\', and \'\-t\' tracking Directives and has no effect without one
996
This is useful, for example, if one of the device Attributes is the disk
997
temperature (usually Attribute 194 or 231). It\'s annoying to get reports
998
each time the temperature changes. This Directive may appear multiple
999
times for a single device, if you want to ignore multiple Attributes.
1002
When tracking, report the \fIRaw\fP value of Attribute \fBID\fP along
1003
with its (normally reported) \fINormalized\fP value. \fBID\fP must be
1004
a decimal integer in the range from 1 to 255. This Directive modifies
1005
the behavior of the \'\-p\', \'\-u\', and \'\-t\' tracking Directives
1006
and has no effect without one of them. This Directive may be given
1009
A common use of this Directive is to track the device Temperature
1010
(often ID=194 or 231).
1012
If the optional flag \'!\' is appended, a change of the Normalized
1013
value is considered critical. The report will be logged as LOG_CRIT
1014
and a warning email will be sent if \'-m\' is specified.
1018
When tracking, report whenever the \fIRaw\fP value of Attribute
1019
\fBID\fP changes. (Normally \fBsmartd\fP only tracks/reports changes
1020
of the \fINormalized\fP Attribute values.) \fBID\fP must be a decimal
1021
integer in the range from 1 to 255. This Directive modifies the
1022
behavior of the \'\-p\', \'\-u\', and \'\-t\' tracking Directives and
1023
has no effect without one of them. This Directive may be given
1026
If this Directive is given, it automatically implies the \'\-r\'
1027
Directive for the same Attribute, so that the Raw value of the
1028
Attribute is reported.
1030
A common use of this Directive is to track the device Temperature
1031
(often ID=194 or 231). It is also useful for understanding how
1032
different types of system behavior affects the values of certain
1035
If the optional flag \'!\' is appended, a change of the Raw
1036
value is considered critical. The report will be logged as
1037
LOG_CRIT and a warning email will be sent if \'-m\' is specified.
1038
An example is \'-R 5!\' to warn when new sectors are reallocated.
1042
[ATA only] Report if the current number of pending sectors is
1043
non-zero. Here \fBID\fP is the id number of the Attribute whose raw
1044
value is the Current Pending Sector count. The allowed range of
1045
\fBID\fP is 0 to 255 inclusive. To turn off this reporting, use
1046
ID\ =\ 0. If the \fB\-C ID\fP option is not given, then it defaults to
1047
\fB\-C 197\fP (since Attribute 197 is generally used to monitor
1050
If \'+\' is specified, a report is only printed if the number of sectors
1051
has increased between two check cycles. Some disks do not reset this
1052
attribute when a bad sector is reallocated.
1053
See also \'\-v 197,increasing\' below.
1055
A pending sector is a disk sector (containing 512 bytes of your data)
1056
which the device would like to mark as ``bad" and reallocate.
1057
Typically this is because your computer tried to read that sector, and
1058
the read failed because the data on it has been corrupted and has
1059
inconsistent Error Checking and Correction (ECC) codes. This is
1060
important to know, because it means that there is some unreadable data
1061
on the disk. The problem of figuring out what file this data belongs
1062
to is operating system and file system specific. You can typically
1063
force the sector to reallocate by writing to it (translation: make the
1064
device substitute a spare good sector for the bad one) but at the
1065
price of losing the 512 bytes of data stored there.
1069
[ATA only] Report if the number of offline uncorrectable sectors is
1070
non-zero. Here \fBID\fP is the id number of the Attribute whose raw
1071
value is the Offline Uncorrectable Sector count. The allowed range of
1072
\fBID\fP is 0 to 255 inclusive. To turn off this reporting, use
1073
ID\ =\ 0. If the \fB\-U ID\fP option is not given, then it defaults to
1074
\fB\-U 198\fP (since Attribute 198 is generally used to monitor
1075
offline uncorrectable sectors).
1077
If \'+\' is specified, a report is only printed if the number of sectors
1078
has increased since the last check cycle. Some disks do not reset this
1079
attribute when a bad sector is reallocated.
1080
See also \'\-v 198,increasing\' below.
1082
An offline uncorrectable sector is a disk sector which was not
1083
readable during an off\-line scan or a self\-test. This is important
1084
to know, because if you have data stored in this disk sector, and you
1085
need to read it, the read will fail. Please see the previous \'\-C\'
1086
option for more details.
1089
.B \-W DIFF[,INFO[,CRIT]]
1090
Report if the current temperature had changed by at least \fBDIFF\fP
1091
degrees since last report, or if new min or max temperature is detected.
1092
Report or Warn if the temperature is greater or equal than one of
1093
\fBINFO\fP or \fBCRIT\fP degrees Celsius.
1094
If the limit \fBCRIT\fP is reached, a message with loglevel
1095
\fB\'LOG_CRITICAL\'\fP will be logged to syslog and a warning email
1096
will be send if '-m' is specified. If only the limit \fBINFO\fP is
1097
reached, a message with loglevel \fB\'LOG_INFO\'\fP will be logged.
1099
If this directive is used in conjunction with state persistence
1100
(\'\-s\' option), the min and max temperature values are preserved
1101
across boot cycles. The minimum temperature value is not updated
1102
during the first 30 minutes after startup.
1104
To disable any of the 3 reports, set the corresponding limit to 0.
1105
Trailing zero arguments may be omitted. By default, all temperature
1106
reports are disabled (\'-W 0\').
1108
To track temperature changes of at least 2 degrees, use:
1112
To log informal messages on temperatures of at least 40 degrees, use:
1116
For warning messages/mails on temperatures of at least 45 degrees, use:
1120
To combine all of the above reports, use:
1125
For ATA devices, smartd interprets Attribute 194 as Temperature Celsius
1126
by default. This can be changed to Attribute 9 or 220 by the drive
1127
database or by the \'-v\' directive, see below.
1131
[ATA only] Modifies the behavior of \fBsmartd\fP to compensate for
1132
some known and understood device firmware bug. The arguments to this
1133
Directive are exclusive, so that only the final Directive given is
1134
used. The valid values are:
1137
\- Assume that the device firmware obeys the ATA specifications. This is
1138
the default, unless the device has presets for \'\-F\' in the device
1142
\- In some Samsung disks (example: model SV4012H Firmware Version:
1143
RM100-08) some of the two- and four-byte quantities in the SMART data
1144
structures are byte-swapped (relative to the ATA specification).
1145
Enabling this option tells \fBsmartd\fP to evaluate these quantities
1146
in byte-reversed order. Some signs that your disk needs this option
1147
are (1) no self-test log printed, even though you have run self-tests;
1148
(2) very large numbers of ATA errors reported in the ATA error log;
1149
(3) strange and impossible values for the ATA error log timestamps.
1152
\- In more recent Samsung disks (firmware revisions ending in "\-23") the
1153
number of ATA errors reported is byte swapped. Enabling this option
1154
tells \fBsmartd\fP to evaluate this quantity in byte-reversed order.
1157
\- Some Samsung disks (at least SP2514N with Firmware VF100\-37) report
1158
a self\-test still in progress with 0% remaining when the test was already
1159
completed. If this directive is specified, \fBsmartd\fP will not skip the
1160
next scheduled self\-test (see Directive \'\-s\' above) in this case.
1162
Note that an explicit \'\-F\' Directive will over-ride any preset
1163
values for \'\-F\' (see the \'\-P\' option below).
1166
[Please see the \fBsmartctl \-F\fP command-line option.]
1169
.B \-v ID,FORMAT[:BYTEORDER][,NAME]
1170
[ATA only] Sets a vendor\-specific raw value print FORMAT, an optional
1171
BYTEORDER and an optional NAME for Attribute ID.
1172
This directive may be used multiple times.
1173
Please see \fBsmartctl -v\fP command-line option for further details.
1175
The following arguments affect smartd warning output:
1178
\- Raw Attribute number 197 (Current Pending Sector Count) is not
1179
reset if uncorrectable sectors are reallocated. This sets \'-C 197+\'
1180
if no other \'-C\' directive is specified.
1183
\- Raw Attribute number 198 (Offline Uncorrectable Sector Count) is not
1184
reset if uncorrectable sector are reallocated. This sets \'-U 198+\'
1185
if no other \'-U\' directive is specified.
1191
should use any preset options that are available for this drive. The
1192
valid arguments to this Directive are:
1195
\- use any presets that are available for this drive. This is the default.
1198
\- do not use any presets for this drive.
1201
\- show the presets listed for this drive in the database.
1204
\- show the presets that are available for all drives and then exit.
1208
command-line option.]
1212
Equivalent to turning on all of the following Directives:
1214
to check the SMART health status,
1216
to report failures of Usage (rather than Prefail) Attributes,
1218
to track changes in both Prefailure and Usage Attributes,
1219
.B \'\-l\ selftest\'
1220
to report increases in the number of Self-Test Log errors,
1222
to report increases in the number of ATA errors,
1224
to report nonzero values of the current pending sector count, and
1226
to report nonzero values of the offline pending sector count.
1228
Note that \-a is the default for ATA devices. If none of these other
1229
Directives is given, then \-a is assumed.
1233
Comment: ignore the remainder of the line.
1236
Continuation character: if this is the last non-white or non-comment
1237
character on a line, then the following line is a continuation of the current
1240
If you are not sure which Directives to use, I suggest experimenting
1241
for a few minutes with
1243
to see what SMART functionality your disk(s) support(s). If you do
1244
not like voluminous syslog messages, a good choice of
1246
configuration file Directives might be:
1248
.B \-H \-l\ selftest \-l\ error \-f.
1250
If you want more frequent information, use:
1254
.B ADDITIONAL DETAILS ABOUT DEVICESCAN
1255
If a non-comment entry in the configuration file is the text
1256
string \fBDEVICESCAN\fP in capital letters, then \fBsmartd\fP will
1257
ignore any remaining lines in the configuration file, and will scan
1260
[NEW EXPERIMENTAL SMARTD FEATURE] Configuration entries for devices
1261
not found by the platform\-specific device scanning may precede the
1262
\fBDEVICESCAN\fP entry.
1264
If \fBDEVICESCAN\fP is not followed by any Directives, then smartd
1265
will scan for both ATA and SCSI devices, and will monitor all possible
1266
SMART properties of any devices that are found.
1268
\fBDEVICESCAN\fP may optionally be followed by any valid Directives,
1269
which will be applied to all devices that are found in the scan. For
1272
.B DEVICESCAN -m root@example.com
1274
will scan for all devices, and then monitor them. It will send one
1275
email warning per device for any problems that are found.
1277
.B DEVICESCAN -d ata -m root@example.com
1279
will do the same, but restricts the scan to ATA devices only.
1281
.B DEVICESCAN -H -d ata -m root@example.com
1283
will do the same, but only monitors the SMART health status of the
1284
devices, (rather than the default \-a, which monitors all SMART
1288
.B EXAMPLES OF SHELL SCRIPTS FOR \'\-M exec\'
1289
These are two examples of shell scripts that can be used with the \'\-M
1290
exec PATH\' Directive described previously. The paths to these scripts
1291
and similar executables is the PATH argument to the \'\-M exec PATH\'
1294
Example 1: This script is for use with \'\-m ADDRESS -M exec PATH\'. It appends
1297
to the output of the smartd email warning message and sends it to ADDRESS.
1303
# Save the email message (STDIN) to a file:
1306
# Append the output of smartctl -a to the message:
1307
/usr/local/sbin/smartctl -a -d $SMART_DEVICETYPE $SMARTD_DEVICE >> /root/msg
1309
# Now email the message to the user at address ADD:
1310
/bin/mail -s "$SMARTD_SUBJECT" $SMARTD_ADDRESS < /root/msg
1314
Example 2: This script is for use with \'\-m <nomailer> \-M exec
1315
PATH\'. It warns all users about a disk problem, waits 30 seconds, and
1316
then powers down the machine.
1322
# Warn all users of a problem
1323
wall \'Problem detected with disk: \' "$SMARTD_DEVICESTRING"
1324
wall \'Warning message from smartd is: \' "$SMARTD_MESSAGE"
1325
wall \'Shutting down machine in 30 seconds... \'
1327
# Wait half a minute
1330
# Power down the machine
1331
/sbin/shutdown -hf now
1335
Some example scripts are distributed with the smartmontools package,
1336
in /usr/local/share/doc/smartmontools-5.1/examplescripts/.
1338
Please note that these scripts typically run as root, so any files
1339
that they read/write should not be writable by ordinary users or
1340
reside in directories like /tmp that are writable by ordinary users
1341
and may expose your system to symlink attacks.
1343
As previously described, if the scripts write to STDOUT or STDERR,
1344
this is interpreted as indicating that there was an internal error
1345
within the script, and a snippet of STDOUT/STDERR is logged to SYSLOG.
1346
The remainder is flushed.
