How about adding entries to your mdadm.conf file containing the UUID
of /dev/md0, eg:

ARRAY /dev/md8 level=raid6 num-devices=16
UUID=38a06a50:ce3fc204:728edfb7:4f4cdd43

note this should be all one line.

I'll be happy to do that.

mdadm -D /dev/md0 should get you the UUID.

	root@00144ff2a334:/# mdadm -D /dev/md0
	mdadm: md device /dev/md0 does not appear to be active.

So...how do I get the UUIDs?  I tried blkid and got this.

Those UUIDs are far from unique.

	After all your drives are visible, of course:

`mdadm --examine /dev/sd* /dev/hd* > <filename>`
`more <filename>`

Make note of the array UUID for each drive.  When done,

`mdadm --assemble --assume-clean /dev/mdX /dev/<drive0> /dev/<drive1>
/dev/<drive2> ...etc`

where <drive0>, <drive1>, etc are all members of the same array UUID.

	Mount the file system, and fsck it.  Once everything is verified
good,

`echo repair > /sys/block/mdX/md/sync_action`
`mdadm --examine --scan >> /etc/mdadm/mdadm.conf`
