ANNOUNCE-2.0

   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
   4    mdadm version 2.0
   5
   6 It is available at the usual places:
   7    http://www.cse.unsw.edu.au/~neilb/source/mdadm/
   8 and
   9    http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/
  10
  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.
  14
  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).
  23
  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.
  28
  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
  31 production systems.
  32
  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.
