Hi Blair,
When mdadm manages an IMSM array it treats it as a 'container' and 1 or more
'arrays'.
What you see as /dev/md/imsm0 is the container. It looks correct.
You should see the array too: /dev/md/VIDEODATA
Do you see that?
It is mentioned in the "-Asvv" output, but that doesn't look quite like what
I would expect, so maybe you are running an older version of mdadm than the
code I am looking at.
What version do you have: "mdadm -V".
If you don't have /dev/md/VIDEODATA, try:
mdadm -Ivv /dev/md/imsm0
and see what that results in.
Also, what does
cat /proc/mdstat
show?
Do you have an '/etc/mdadm.conf'? If so, what is in it?
