Hi!
I have find myself in a troublesome spot. After a disk failure, with
lots of IDE bus timeouts etc i managed to get the disk in error replaced
and my raid5 set in full operation. But i can't get the volume group
active any more. The volume group in question is VG1.
I have read one year worth of messages in this list archives, and i
still can't se how i can recover my VG1.
Please find the details below
