Subject: ANNOUNCE: mdadm 2.4-pre1 - development release for testing only
3
I am somewhat cautious in announcing the availability of
6
It is available at the usual places:
7
http://www.cse.unsw.edu.au/~neilb/source/mdadm/
9
http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/
11
pre-release 2.4-pre1 contains support for growing a raid5 array i.e.
12
adding extra drives and restriping the whole arrays.
14
This requires a kernel more recent than 2.6.16-rc6-mm2.
16
During a restripe, there is a crtical section at the start where a
17
system crash can leave the contents of the raid5 unrecoverable. This
18
version of mdadm will backup that section, and can restore it when
19
reassembling the array after a crash.
21
Have fun, but use it carefully and report any problems.
