ANNOUNCE: mdadm 3.1 - A tool for managing Soft RAID under Linux

[Neil Brown]

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:
   countrycode=xx.
   http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
and via git at
   git://neil.brown.name/mdadm
   http://neil.brown.name/git?p=mdadm


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
        back.
   -    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
features.

Why is that? because its more untested than older versions, or because
of some other thing? i guess what im asking is, should people that dont
need these features keep on the older branches indefinitely, or just
hold off for some more testing? (aka grab it when the distribution
update arrives)

"just hold off for some more testing".

The new functionality in 3.1 is still very fresh and I would rather
people had to make a deliberate decision to install the new code in
order to use it, rather than just finding that it works and assuming
that it is completely reliable.

I have received some very valuable feedback on 3.1 already and will
fix a number of issues in 3.1.1.  At that point I suspect I will
suggest people upgrade.

Thanks,
NeilBrown
