[EMAIL PROTECTED] ~]# mdadm /dev/md0 --verbose --add /dev/hdd1
mdadm: added /dev/hdd1
HUGE thanks to Neil, and one white gold plated donkey award to me.
OK. When I created /dev/md1 after creating /dev/md0, I was using a
mishmash of disks I had lying around. As this selection of disks used
differing block sizes, I chose to create the raid partitions from the
first block, to a set size (+250G). When I reinstalled the disk for
going into /dev/md0, I partitioned the disk the same way (+500G), which
it turns out isn't how I created the partitions when I created that
array.
So the device I was trying to add was about 22 blocks too small. Taking
Neils suggestion and looking at /proc/partitions showed this up
incredibly quickly.
My sincere apologies for wasting all your time on a stupid error, and
again many many thanks for the solution...
