This cannot work in case of split brain.
Therefore, some primary must be designated always explicitly.

marsadm: allow overrides of "marsadm secondary" in disconnected clusters
...
When the communication is down in partitioned clusters, the command
"marsadm seconodary" would normally use the current timestamp of
the command execution for the Lamport update protocol.
Make an exception for the case that a concurrent "marsadm primary"
was given somewhere else on a disconnected / partitioned node: let
the "primary" always win over a "secondary" command.

DRBD does not allow to deliberately provoke a SPLIT BRAIN

Thus MARS Light cannot be required to support such silly things

marsadm: fix leave-resource cleanup
...
Now the sequence leave-resource ; join-resource should work.
When the last member of the resource has gone and create-resource is
tried anew, there is a new saftey measure: the old resource directory
is left over deliberately, thus the new create-resource will deny creation
because some unreachable cluster node may have existed, such that we
didn't even know of its resource membership. This very special
case requires --force and some handwork cleanup.
