If you want to wipe the drbd partition, just format it directly and the metadata space will be
accounted for automatically.
Simply do:
mke2fs -j /dev/drbd0
However, if you can keep metadata in a separate partition, it would be a lot better and you will be
able to blank your drbd partition using dd. The default meatadata size is 128MB per drbd partition,
so make sure that you create a partition with enough space for as many drbd partitions as you will
have. A 1024MB partition for drbd metadata should be good for up to 8 devices.
