X-Git-Tag: v3.2-rc1~115^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7fcc7c8acf0fba44d19a713207af7e58267c1179;p=pandora-kernel.git md/raid10: Fix bug when activating a hot-spare. This is a fairly serious bug in RAID10. When a RAID10 array is degraded and a hot-spare is activated, the spare does not take up the empty slot, but rather replaces the first working device. This is likely to make the array non-functional. It would normally be possible to recover the data, but that would need care and is not guaranteed. This bug was introduced in commit 2bb77736ae5dca0a189829fbb7379d43364a9dac which first appeared in 3.1. Cc: stable@kernel.org Signed-off-by: NeilBrown --- Reading git-diff-tree failed
