I'm surprised it didn't complain either, which is frustrating. I'm the
dumb-a** that didn't keep my data longer, but it would have been nice to
know the array wasn't created correctly.
What command would I use for to force it? I don't want to do anything
wrong and make my bad situation worse. If I try this I get:
[root at storage ~]# mdadm --force --assemble /dev/md0 /dev/hdb /dev/hdc
mdadm: --assemble would set mdadm mode to "assemble", but it is already set to "manage".
What command(s) should I be using?
Thanks,
James
