Subject: Grow: fix bug in raid0 -> raid5 conversion.
X-Git-Tag: mdadm-3.3-rc2~99
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dea3786ae2cf74ecb0087d1bea1aa04e9091ad5c;p=thirdparty%2Fmdadm.git

Grow: fix bug in raid0 -> raid5 conversion.

The moment we change a RAID0 to a RAID5 it will try to recovery.  This
will abort quite quickly as there are not spare devices, but it could
confuse the attempt to freeze the array.

So allow 'freeze' to work even on a recovering array.
