Message-Id: <1070123002652.29462@suse.de> Date: Tue, 23 Jan 2007 11:26:52 +1100 From: NeilBrown <neilb@...e.de> To: Andrew Morton <akpm@...l.org> Cc: linux-raid@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 002 of 4] md: Make 'repair' actually work for raid1. When 'repair' finds a block that is different one the various parts of the mirror. it is meant to write a chosen good version to the others. However it currently writes out the original data to each. The memcpy to make all the data the same is missing.
