verify

Low-level check that a drive, logical device, or hot spare is good. In a RAID 5, verify is a low-level check that data and parity is consistent and logs errors and, optionally, corrects errors in parity. In a RAID 1, verify is a low-level check that contents of both members segments are consistent and, optionally, corrects errors while assuming that the master drive is correct. For a drive (and hot spare) verify performs a low-level check that the whole drive can be read.
