I can force mount /dev/sda2 or /dev /sdb1 to mount as ext3 and I can
read the data just fine.
If the data is fine, I would assemble the array in degraded mode using
just one of the two drives, then hot-add the 2nd one later.
Exactly.
It's the only choice he has right now anyway, given that he has
corrupted the mirror by mounting the sda/sdb devices separately (they
now hold divergent data, and trying to assemble both into a mirror would
crash).
Backup the data. Start the mirror in degraded mode with one drive. Wipe
the other drive. Add it to the mirror (which will do a full resync).
And then don't do it again ;-)
Regards,
Lars
