Subject: ANNOUNCE: mdadm 3.2.4 - A tool for managing Soft RAID under Linux
|
|
|
|
I am pleased to announce the availability of
|
|
mdadm version 3.2.4
|
|
|
|
It is available at the usual places, now including github:
|
|
countrycode=xx.
|
|
http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
|
|
and via git at
|
|
git://github.com/neilbrown/mdadm
|
|
git://neil.brown.name/mdadm
|
|

|
|
|
|
This release is largely a bugfix release for the 3.2 series with many
|
|
minor fixes with little or no impact.
|
|
|
|
"--oneline" log of changes is below. Some notable ones are:
|
|
|
|
- --offroot argument to improve interactions between mdmon and initrd
|
|
- --prefer argument to select which /dev names to display in some
|
|
circumstances.
|
|
- relax restructions on when "--add" will be allowed
|
|
- Fix bug with adding write-intent-bitmap to active array
|
|
- Now defaults to "/run/mdadm" for storing run-time files.
|
|
|
|
Upgrading is encouraged.
|
|
|
|
The next mdadm release is expected to be 3.3 with a number of new
|
|
features.
