Hello all,
I've got a helluva problem and I'm hoping someone here can possibly help
out.
I've got raid5 (sdb1,sbc1,sdd1) on a partition, and one of the drives
(sdd1) went bad. So I (stupidly) hit the reset button on the computer,
but now the partition won't mount. Raid complains that one drive is bad
(which it is), and that the other is out of sync. See part of dmesg
below...
Am I hosed? Can I fake out raid by commenting out some of the code that
tries to determine whether or not the drive is fresh?
Thanks,
Monty
