Hello, As I know if MD raid is using the newer metadata version, it support resumable raid rebuild/sync. (that is, if a server is rebooted during rebuild, it would resume from last position after reboot, instead of starting from beginning). In my recently testing (a few months ago): I sometimes use the mdadm 'check' action for doing the disk scrubbing of a MD raid. After I rebooted the server, the 'check' operation is forgotten and is not resumable. I think resumable 'check' operation is useful as the array size would become bigger in the future.
