This is not correct:
st:Primary/Unknown and st:Secondary/Unknown
The correct is:
st:Secondary/Secondary in both nodes.
The partition is probably the problem. If now the data is not important do:
Delete the partitions created for drbd. they should be create without file system (you can use gparted). Partition type primary, no format, without format (no ext3, ext2, etc)...
in both nodes:
drbdadm attach r0
drbdadm create-md r0
drbdadm connect r0
in one node:
drbdadm -- --overwrite-data-of-peer primary r0
