	I have no idea.

I just spotted something not quite right.  Line 7 is missing a drive 
(/dev/sda).   That shouldn't prevent it from assembling, though.

	Oh, sorry!  I thought the fact I got it to assemble meant I didn't need to 
issue the command again...

	Indeed, it won't let me issue it again.  it says:

RAID-Server:/etc/cron.d# mdadm -A /dev/md0 /dev/sd[a-j] -vvv
mdadm: device /dev/md0 already active - cannot assemble it

	Should I stop the arraya nd re-assemble it with -vvv?

	Also, what about my question about the bitmap?  Should I delete it, despite 
the fact mdadm says there isn't one, or should I attempt to add it again, or 
should I wait until I do the checkarrray?
