Subject: ANNOUNCE: mdadm 3.2.4 - A tool for managing Soft RAID under Linux
Newsgroups: gmane.linux.raid
Date: Wednesday 9th May 2012 01:29:37 UTC (over 4 years ago)
I am pleased to announce the availability of
   mdadm version 3.2.4

It is available at the usual places, now including github:
and via git at

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
 - 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
