it is just an educated guess, but:
you created your file system on the lower level device.
you put drbd on top of that, using "meta-disk internal".
you did not shrink your file system before that.
oops.

recover:
  secondary# heartbeat stop
  primary# heartbeat stop
  
  verify drbd is Secondary/Secondary
  
  both# drbdadm down all
  
  verify drbd is Unconfigured
  
  good-data# fsck /dev/lower-level
  
  shrink the file system.
  good-date# "whatever-resize" /dev/lower-level minus-130MB
  
  both# start drbd.
  
  other-node# drbdadm invalidate all
  
  wait for full sync
  
  both# start heartbeat.

or, since you are in openvz, maybe you just want to redeploy?
