I tried that too Neil, it said:

nemtemp:/mnt # mdadm --verbose --assemble --force --update=no-bitmap /dev/md1
/dev/sd[ab]5
mdadm: '--update=no-bitmap' is invalid.  Valid --update options are:
     'sparc2.2', 'super-minor', 'uuid', 'name', 'resync',
     'summaries', 'homehost', 'byteorder', 'devicesize'.

Like in my reply to Adam, I think the age of mdadm may be the issue. The
openSuSE 11.0 install DVD is pretty old ;-) It just may not be handling the
- --assemble correctly given the Event count difference, and there doesn't seem to
be a way to just tell it:

"The data is correct on both disks, just assemble and run it and be quiet!"

I'll try booting an Arch install CD with 3.3.2 on it and report back. Thank you
and Adam for your help.

If it does assemble with mdadm 3.3.2, anything I need to do on the assembled
array to make sure it stays that way? fsck? Any way to tell it to make sure it
is in sync so it will boot under the openSuSE 11.0 version of mdadm?
