It is mirrored, do you understand what that means? It means that if your
filesystem screws up and writes crap to one drive, raid will faithfully
write crap to the mirror copy, thereby giving you a fully reliable fully
hosed filesystem. Your problem isn't that your raid array has lost your
data, but rather that your filesystem has been trashed. And from your
comments in another post about reinstalling jfs utilities, I suspect
that a nice clean removal of those utilities has some element of human
intervention involved.
