Subject: [PATCH] imsm: set generation number when reading superblock
Date: Thu, 8 Dec 2016 12:12:48 +0100 [thread overview]
Message-ID: <1481195568-12973-1-git-send-email-mariusz.dabrowski@intel.com> (raw)
IMSM doesn't set 'events' field with generation number, so sometimes mdadm
tries to re-assembly container using metadata which isn't most recent (e. g.
from spare disk).
