there you are.  that is the reason.

first uuid differs, other (bitmap, history) uuids are identical:
data set has been modified independently, split-brain detected...

to resolv this, you have to tell drbd
which of the independen modifications
of the data set you want to discard.

to do so:
  cricket# drbdadm -- --discard-my-data connect all
  magratea# drbdadm connect all
should do the trick.

now, we probably should be able to auto-resolv this
if one side is "inconsistent", as is aparently the case here.
