I had a similar problem when I first started working with drbd long ago, and it was due to the fact 
that I had formated the partition on the real device and not the drbd device.  This occurs 
specifically if you are using internal metadata.

If you are using internal metadata, then you should format the drbd partition again so that things 
work fine and the last 128MB of the partition are kept untouch for the metadata.

1. Backup all data to another partition
2. With drbd up format the drbd partition mke2fs -j /dev/drbdX
    -j if you want ext3.
3. put all data back in the partition.

That should take care of it.
