This software discovers, activates, deactivates and displays properties
13
of software RAID sets (eg, ATARAID) and contained DOS partitions.
15
dmraid uses libdevmapper and the device-mapper kernel runtime to create
16
devices with respective mappings for the ATARAID sets discovered.
18
The following ATARAID types are supported:
32
Beside hints, enhancement proposals and patches, I want to know, if the mappings
33
the tool creates ("dmraid -tay") are correct for your ATARAID configuration.
35
Thank you for your support of dmraid.

This software is released under the GPL/LGPL respectively.
42
See file headers, LICENSE, LICENSE_GPL and LICENSE_LGPL for details.
44
This is Alpha software and it can destroy your data!
46
So please take backups and start accessing your data in dmraid
47
activated ATARAID sets READ-ONLY first before you try to write it!

Minimum prerequisites to run this software:
51
-------------------------------------------
53
o a recent mainline Linux 2.6 kernel (includes needed
54
device-mapper mirror changes)
57
Additional minimum prerequisites to build this software:
58
--------------------------------------------------------
59
o device mapper userpace installed (http://sources.redhat.com/dm/)
61
o the i386 rpm or source tarball for dmraid from
62
http://people.redhat.com/heinzm/sw/dmraid/
69
rpm -i [--nodeps] dmraid-1.0.0.rc15.i386.rpm
73
to build in an empty directory and install from source
75
tar jxvf dmraid-1.0.0.rc15.tar.bz2
76
./configure # see ./configure --help for options
81
In case you want to dietize dmraid, you need to build device-mapper with
82
'make CC="diet cc"' *and* install libdevmapper.a as /lib/libdevmapper_dietc.a.
84
Run "./configure --enable-dietlibc" before make.
89
See "dmraid -h" for the synopsis and "man dmraid" for more details
90
including some usage examples.
92
Your first command is probably "dmraid -s".
94
See TODO for known outstanding issues.
96
See doc/dmraid_design.txt for design notes.
98
See lib/format/template/ if you want to start your own metadata format
99
handler implementation :)
