Subject: [PATCH 2/4] raid0->raid10 takeover- create metadata update
Date: Mon, 17 Jan 2011 16:42:52 +0100	[thread overview]
Message-ID: <20110117154252.25096.22110.stgit@gklab-128-111.igk.intel.com> (raw)
In-Reply-To: <20110117153908.25096.42697.stgit@gklab-128-111.igk.intel.com>

Create metadata update for raid0 -> raid10 takeover.
Because we have no mdmon running for raid0 we have to
update metadata using local update mechanism
