I have two identical disks that were in a raid configuration in another
machine (also running 10.04). I removed them from the old machine, mounted
them in a new machine, booted up, and at a terminal prompt as root issued
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb /dev/sdc
Did you mean create or assemble?
If you used create it would have nuked all the data - including partition
table and filesystem..
... actually, I don't know the precise mechanism for a create on raid 1 -
if it just copies one disk to the other, then the data might well be
intect if you can recover the partition table, but if it writes zeros to
both disks then you're out of luck ...
