You don't need to care about the striping, as both the Disks are exact clones of each other. So you can simply pull out the healthy disk and start using it as a single drive OR you can push in another healthy disk to replace the dead one and rebuild the volume. However if you are using a RAID controller card, the hardware would do the rebuilding for you. Refer to the Vinum volume manager section of the handbook. > PS: CC my for I�m not on the list.

BTW I personally feel its worthwhile to subscribe even if you dont want or not capable to asnwer questions because you can learn from others problems and save hours of troubleshoting later.
