volume recovery question

volume recovery question

[scowles]

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?
