ConfigImportDiskState
matched: exactly one attached disk carries the recorded identity (WWN, else serial; a weak-identity disk by filesystem UUID and size) and its filesystem is the recorded one. absent: no attached disk is it. replaced: the identity or the filesystem differs, either an attached disk holds the recorded filesystem with another identity or the disk with the recorded identity holds another filesystem. ambiguous: more than one attached disk matches, a disk and its clone. A disk that is not matched stays a row of the restored array with its recorded filesystem, is never mounted or adopted by the restore, and leaves the array degraded.
