I have had a machine to go into degraded mode from whence it does recover automatically at next power restart, but the thing recovers wrong disk, e.g. leaps back in time! (The disk is failing by 'Failure prediction threshold exceeded', and gets back online at next powerup..) Apparently when a disk fails from under RAID1, the disks that are left into running the set are not marked with a NEW serial number in superblock so that auto-recovery won't pick obsolete data in case such becomes available. /Matti Aarnio - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
