Yeah. I expect that scrub can both detect disk errors and check data integrity (based on the checksum) in the background. For disk errors, I would like CEPH to mark the OSD down/failed and notify the sys admin immediately. For data errors, I expect that CEPH can repair them automatically (by fetching a right copy from other replicas). -- Henry Chang -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
