Phil,
phew I didn't know that:
"mdadm: /dev/sdo has wrong uuid.
mdadm: /dev/sdn1 has wrong uuid."

was just that the array UUID didn't match mdadm.conf, it would be nice 
if it said:

"mdadm: /dev/sdo uuid does not match mdadm.conf.
mdadm: /dev/sdn1 uuid does not match mdadm.conf"
my mdadm.conf now reads

DEVICE partitions
CREATE owner=root group=disk mode=0660 auto=yes
HOMEHOST <system>
MAILADDR root
# ARRAY /dev/md/0 level=raid5 metadata=1.1 num-devices=10 
UUID=0a72e40f:aec6f80f:a7004457:1a84a7a8 name=pro�lox:0
ARRAY /dev/md/0 metadata=1.1 UUID=12c2af00:10681e10:fb17e449:1404739c 
name=proxmox:0

I'm afraid to do another reboot incase something else goes wrong ;-).  
Just for my info, when I only have a single array there isn't much 
chance of it being assigned anything other than md0, so could I not just 
leave mdadm.conf empty ?
cheers

Simon
