So the new disks will be sd[efgh]1.
But when I pull the old drives after migrating, they will be sd[abcd]1.. so...
how do I handle this?
Make an mdadm.conf file that reflects your current array and use UUID's
to identify the arrays - here is an example:
ARRAY /dev/md5 level=raid5 num-devices=4
UUID=32cd6355:3c2c08a3:970a9f77:c13e51a3
Note, this should be all one line.
This will ensure that regardless of which /dev/sdX a drive is, the array
will be assembled only from drives which are using this UUID.
mdadm -D /dev/mdX where X is your current array will give you the UUID
of this array.
