Subject: [PATCH 0/9] raid5-cache fixes
Date: Thu, 8 Oct 2015 21:54:04 -0700 [thread overview]
Message-ID: <cover.1444360850.git.shli@fb.com> (raw)
Hi,
some fixes for raid5-cache/md. Mainly supports trim, handle IO error and
handling array assemble with missing/faulty disks.
patch 1: fix a bug
patch 2: support trim
patch 3-4, IO error handling
patch 5-9, handle assemble issue when journal disk is missing/faulty
If there is IO error to journal disk, write IO will fail immediately. If we
assemble an array with journal feature enabled but with journal disk
missing/faulty, the raid array will start readonly.
Thanks,
Shaohua
