Subject: [PATCH] Monitor: don't set arrays dirty after transition to read-only
Date: Sat, 14 Sep 2013 23:24:07 +0200 [thread overview]
Message-ID: <1379193847-402-1-git-send-email-mwilck@arcor.de> (raw)
In-Reply-To: <5234D221.8010607@arcor.de>
This patch reverts commit 4867e068. Setting arrays dirty after
transition from inactive to anything else causes unnecessary
meta data writes and may wreak trouble unnecessarily when
a disk was missing during assembly but the array was never
written to.
The reason for 4867e068 was a special situation during reshape
from RAID0 to RAID4. I ran all IMSM test cases with it reverted
and found no regressions, so I believe the reshape logic for
IMSM works fine in mdadm 3.3 also without this.
