|
|
|
|
I am pleased to announce the availability of
|
|
mdadm version 2.4
|
|
|
|
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 2.4 primarily adds support for increasing the number of
|
|
devices in a RAID5 array, which requires 2.6.17 (or some -rc or -mm
|
|
prerelease).
|
|
It also includes a number of minor functionality enhancements and
|
|
documentation updates.
|
|
|
|
Changelog Entries:
|
|
- Rewrite 'reshape' support including performing a backup
|
|
of the critical region for a raid5 growth, and restoring that
|
|
backup after a crash.
|
|
- Put a 'canary' at each end of the backup so a corruption
|
|
can be more easily detected.
|
|
- Remove useless 'ident' arguement from ->getinfo_super method.
|
|
- Support --backup-file for backing-up critical section during
|
|
growth.
|
|
- Erase old superblocks (of different versions) when creating new
|
|
array.
|
|
- Allow --monitor to work with arrays with >28 devices
|
|
- Report reshape information in --detail
|
|
- Handle symlinks in /dev better
|
|
- Fix mess in --detail output which a device is missing.
|
|
- Manpage tidyup
|
|
- Support 'bitmap=' in mdadm.conf for auto-assembling arrays with
|
|
write-intent bitmaps in separate files.
|
|
- Updates to md.4 man page including section on RESTRIPING and SYSFS
