   2
   3 I am pleased to announce the availability of
   4    mdadm version 2.3
   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 2.3 fixes an assortment of bugs including the "--assemble --scan"
  16 crash.  It also makes mdadm better at handling very large arrays.
  17 Finally, it adds some functionality to support some pending kernel
  18 features such as raid5 reshaping.

  20 Changelog Entries:
  21     -   Try /etc/mdadm/mdadm.conf if /etc/mdadm.conf doesn't exist.
  22         This provided compatability for Debian.
  23     -   Fixed for version-1 superblock:
  24          report chunksize for raid6 and raid10
  25          make sure device size used is a multiple of chunksize
  26     -   Fix "--assemble --scan" crash.
  27     -   Fix completely failure to create array on ppc64
  28     -   Fix memcmp in place of memcpy
  29     -   A few minor improvements to online help
  30     -   Clean up usage of 'long long' for used-size of devices, so
  31         that it is possible to create a raid1 of 7TB devices!
  32     -   Make internal bitmaps work on 7TB raid1 arrays.
  33     -   Provide error message if --examine doesn't find any superblock.
  34     -   Report 'reshape' status in --examine - this depends on kernel
  35         patches that are not yet finalised.
  36     -   Report bitmap status in --detail and --examine
  37     -   Default to v1 superblocks instead of v0.90 if the array
  38         is too big for 0.90 to handle.
  39     -   Sort the output of "mdadm --detail --scan" so that it is
  40         in a suitable order for assembling arrays. i.e. components come
  41         before an array that they are part of.
  42     -   Print size of large reiserfs array properly went warning of
  43         possible confilcts.
