1 Subject: ANNOUNCE: mdadm 2.0 - A tool for managing Soft RAID under Linux
3 I am (at last) please to announce 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 mdadm is a tool for creating, managing and monitoring
12 device arrays using the "md" driver in Linux, also
13 known as Software RAID arrays.
15 Release 2.0 contains a substantial rewrite of various pieces of
16 functionality, particularly the --create option. This enables support
17 for a new style of superblock - the version-1 superblock.
18 Version-1 can support many more than 28 devices and can be easily
19 moved between hosts with different endian-ness.
20 Release 2.0 also contains support for the recent bitmap-intent-logging
21 which will appear in 2.6.13, and the RAID1 write-behind that will be
22 available in 2.6.14 (it is currently only in -mm).
24 This release comes with a test-suite which has been used to verify that
25 mdadm-2.0 actually works in a number of common scenarios. Some of the
26 tests require a bleeding-edge kernel, so don't be surprised if some fail
27 on kernels prior to 2.6.14.
29 Being a '.0' release, 2.0 should be treated with some caution.
30 However I believe it is quite stable and can safely be used on
33 Note that this release is "2.0", not "2.0.0". I never found a use for
34 the third number with 1.X.Y, so I dropped it.
37 Development of mdadm has moved from CSE@UNSW and is now sponsored by
38 SUSE Labs, Novell Inc.
