Unmount the RAID, Turn off the enclosure. Remove the failing drive, replace it with an identical drive, turn on the enclosure. Open up Disk Utility. Choose the missing drive on the left and then “Demote”. Drag the new disk into the raid set and chose “Rebuild”. You can also do it from the command line: sudo diskutil list sudo diskutil appleraid list sudo diskutil appleraid add member <disk4> <RAID-UUID> where disk4 is the new disk you just added and UUID is the UUID of the RAID set. Note the UUID of the failed disk (listed in the appleraid list above) and then: diskutil appleraid remove DISK-UUID RAID-UUID There is no need to turn off the computer. -- He'd never asked for an exciting life. What he really liked, what he sought on every occasion, was boredom. The trouble was that boredom tended to explode in your face. Just when he thought he'd found it he'd be suddenly involved in what he supposed other people - thoughtless, feckless people - would call an adventure. And he'd be forced to visit many strange lands and meet exotic and colourful people, although not for very long because usually he'd be running. He'd seen the creation of the universe, although not from a good seat, and had visited Hell and the afterlife. He'd been captured, imprisoned, rescued, lost and marooned. Sometimes it had all happened on the same day. _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
