Subject: ANNOUNCE: mdadm 2.3 - A tool for managing Soft RAID under Linux
|
||
|
|
||
|
I am pleased to announce the availability of
|
||
|
mdadm version 2.3
|
||
|
|
||
|
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 2.3 fixes an assortment of bugs including the "--assemble --scan"
|
||
|
crash. It also makes mdadm better at handling very large arrays.
|
||
|
Finally, it adds some functionality to support some pending kernel
|
||
|
features such as raid5 reshaping.
|
||
|
|
||
|
Changelog Entries:
|
||
|
- Try /etc/mdadm/mdadm.conf if /etc/mdadm.conf doesn't exist.
|
||
|
This provided compatability for Debian.
|
||
|
- Fixed for version-1 superblock:
|
||
|
report chunksize for raid6 and raid10
|
||
|
make sure device size used is a multiple of chunksize
|
||
|
- Fix "--assemble --scan" crash.
|
||
|
- Fix completely failure to create array on ppc64
|
||
|
- Fix memcmp in place of memcpy
|
||
|
- A few minor improvements to online help
|
||
|
- Clean up usage of 'long long' for used-size of devices, so
|
||
|
that it is possible to create a raid1 of 7TB devices!
|
||
|
- Make internal bitmaps work on 7TB raid1 arrays.
|
||
|
- Provide error message if --examine doesn't find any superblock.
|
||
|
- Report 'reshape' status in --examine - this depends on kernel
|
||
|
patches that are not yet finalised.
|
||
|
- Report bitmap status in --detail and --examine
|
||
|
- Default to v1 superblocks instead of v0.90 if the array
|
||
|
is too big for 0.90 to handle.
|
||
|
- Sort the output of "mdadm --detail --scan" so that it is
|
||
|
in a suitable order for assembling arrays. i.e. components come
|
||
|
before an array that they are part of.
|
||
|
- Print size of large reiserfs array properly went warning of
|
||
|
possible confilcts.
