i apologize in advance if this is the wrong forum in which to pose this
question. if so, where would it be appropriate?
one disk in a two disk level 1 array failed. i added another disk to the array
and the resynchronisation completed successfully. while the synchronisation was
running, i removed the failed volume and the array filesystem specs vanished.
so i have two questions:
1) what happened when i removed the failed array that caused the existing
filesystem to vanish?
2) is it possible to recovery the filesystem on the array?
