I just lost a disk on my secondary node. I looked EVERYWHERE and can't find
the spare disks I bought for such an occurrence. So, I put in a handy disk,
twice the size.
drbdadm create-md r1
drbdadm attach r1
and off we go.
If memory serves, create-md will build a meta-data at the END of the disk.
Won't that cause a lot of seek to the hub when seeking to about the middle
of the platters would have done the trick, had the metadata been at the same
offset as the primary?
