Subject: [PATCH 0/2] md: Add consistency check feature for level-1 RAID
Date: Mon, 17 Mar 2014 16:00:03 +0100 [thread overview]
Message-ID: <1395068405-13860-1-git-send-email-linux-kernel@rmueck.de> (raw)
This patch series introduces an online consistency check for RAID-1
md-arrays.
The feature compares each block that is read with its pendants on the
other array members to detect silent data corruption (a.k.a. bit rot).
Unfortunately, the feature is not fully-functional at this point, as we
have reached a dead end (see below).
We still want to hand in the patch for reference; maybe you can help
us, for we plan to keep on working on it.
The following issues remain:
- Partitions cannot be mounted with enabled safe read for some reason
(We suppose something goes wrong when duplicating the bio structure)
- Broken sectors during a read result in a crash
- There may be synchronization issues
The following patches apply to the linux-next tree
(rev ed87ead565a6130174fc27a46af65169cbff7677).
