Allow RAID scrubbing on cache origin sub-LV This patch adds the ability to perform RAID scrubbing on the cache origin sub-LV (https://bugzilla.redhat.com/1169495). Cache origin operations are restricted to non-clustered RAID LVs until there can be further testing in a cluster (even for exclusive activation). User can either specify directly _corig LV or he can specify cache LV and operation --syncation is passed ONLY to _corig LV. If users wants to manipulation with cache-pool devices - he needs to specify this object name. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com>
