Subject: ANNOUNCE: mdadm 2.0 - A tool for managing Soft RAID under Linux
|
||
|
|
||
|
I am (at last) please to announce the availability of
|
||
|
mdadm version 2.0
|
||
|
|
||
|
It is available at the usual places:
|
||
|
http://www.cse.unsw.edu.au/~neilb/source/mdadm/
|
||
|
and
|
||
|
http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/
|
||
|
|
||
|
mdadm is a tool for creating, managing and monitoring
|
||
|
device arrays using the "md" driver in Linux, also
|
||
|
known as Software RAID arrays.
|
||
|
|
||
|
Release 2.0 contains a substantial rewrite of various pieces of
|
||
|
functionality, particularly the --create option. This enables support
|
||
|
for a new style of superblock - the version-1 superblock.
|
||
|
Version-1 can support many more than 28 devices and can be easily
|
||
|
moved between hosts with different endian-ness.
|
||
|
Release 2.0 also contains support for the recent bitmap-intent-logging
|
||
|
which will appear in 2.6.13, and the RAID1 write-behind that will be
|
||
|
available in 2.6.14.
|
||
|
|
||
|
This release comes with a test-suite which has been used to verify that
|
||
|
mdadm-2.0 actually works in a number of common scenarios. Some of the
|
||
|
tests require a bleeding-edge kernel, so don't be surprised if some fail
|
||
|
on kernels prior to 2.6.14.
|
||
|
|
||
|
Being a '.0' release, 2.0 should be treated with some caution.
|
||
|
However I believe it is quite stable and can safely be used on
|
||
|
production systems.
|
||
|
|
||
|
|
||
|
Development of mdadm has moved from CSE@UNSW and is now sponsored by
|
||
|
SUSE Labs, Novell Inc.
