Although gdisk says that the partition with the user data is "8300 
Linux filesystem", when I try to mount it after stopping drbd I get

mount: unknown filesystem type 'drbd'

So it looks like I have to wipe out the meta data first. But I need to 
know its offset and size. Unfortunately I cannot understand how to get 
it from the textual dump made by 'drbdmeta dump-md'. The offset 
mentioned there does not seem to point to the meta data.
