Date: Mon, 17 Mar 2014 16:00:03 +0100 From: Ralph Mueck <linux-kernel@...eck.de> To: linux-kernel@...eck.de Cc: i4passt@...ts.cs.fau.de, neilb@...e.de, linux-raid@...r.kernel.org, linux-kernel@...r.kernel.org, Matthias Oefelein <ma.oefelein@...or.de> Subject: [PATCH 0/2] md: Add consistency check feature for level-1 RAID 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).
