Joe / et-al,

The '--assemble --update=uuid' appears to have done the trick. It is
weird because the uuid in the config file matched the uuid of the raid
volume shown with 'mdadm -D /dev/md3' and the uuid on each of the drives
shown with 'mdadm -E /dev/sdc1'

Interesting.


The '--update=summaries' did not work. Assigning a new random uuid
appears to have repaired whatever bit in the superblock was mucked up.

Strange...

Joe, thanks for your help. Find me at SC11, I'm buying you beers.


:)  see you there
