1 Subject: ANNOUNCE: mdadm 2.3 - A tool for managing Soft RAID under Linux
3 I am pleased to announce the availability of
6 It is available at the usual places:

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 2.3 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.
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
