The last two return the same result as #mount.

mount /dev/dm-0 /home/myhome/RAID

I have been using the suspend command on my LXDE manager - - - wondering
if that might have something to do with the problem.

So the array (raid10) is there but it is not getting mounted. The mdadm man
page isn't
very useful for this issue being so terse to be almost useless. There is
really only
information for the establishment and repair but none for remount or any
mounting
issues!

TIA
