157 'dmsetup status' yields information on the state and health of the array.
167 Here we can see the RAID type is raid4, there are 5 devices - all of
169 recovery. Here is a fuller description of the individual fields:
173 <sync_ratio> The ratio indicating how much of the array has undergone
176 of "resync" or "recover" can be considered complete.
177 <sync_action> One of the following possible states:
185 check - A user-initiated full check of the array is
187 checked for consistency. The number of
194 <mismatch_cnt> The number of discrepancies found between mirror copies
196 This value is valid only after a "check" of the array
197 is performed. A healthy array has a 'mismatch_cnt' of 0.
208 "check" - Initiate a check (i.e. a "scrub") of the array.
209 "repair" - Initiate a repair of the array.
