+Hot on the heals of 3.0.3 I am pleased to announce the availability of
+ mdadm version 3.1
+It is available at the usual places:
+and via git at
+It contains significant feature enhancements over 3.0.x
+The brief change log is:
+ - Support --grow to change the layout of RAID4/5/6
+ - Support --grow to change the chunksize of raid 4/5/6
+ - Support --grow to change level from RAID1 -> RAID5 -> RAID6 and
+ - Support --grow to reduce the number of devices in RAID4/5/6.
+ - Support restart of these grow options which assembling an array
+ which is partially grown.
+ - Assorted tests of this code, and of different RAID6 layouts.
+Note that a 2.6.31 or later is needed to have access to these.
+Reducing devices in a RAID4/5/6 requires 2.6.32.
+Changing RAID5 to RAID1 requires 2.6.33.
+You should only upgrade if you need to use, or which to test, these
