I'll see if I can remember the steps: 1) Drive fails (I unplugged the drive's power in my tests) 2) Shutdown 3) Plug new drive in (in same logical location, ie IDE master/slave, SCSI ID, etc). Make sure it's big enough! 4) Boot up 5) fdisk new drive (I use /stand/sysintall for this, and inital label) 6) (re)label new drive slice as Vinum (disklabel -e da?) 7) start vinum and issue "start mirror.p1" (for example, if a drive on plex p1 in volume mirror had failed) Step 7 is the part my memory is fuzzy on, but without looking up my notes on it, I beleive this is correct. Mr. Lehey, do you have anything to add? Voila. As a bonus, the entire Vinum volume is accessable during rebuild. Same procedure for a RAID-10 failure as well. Not sure of the RAID-5 recovery procedure, though. I'd say it was the same, but never ASSume anything because it makes an ASS of U and ME. :-> hth, Jon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
