Better show those parts of the logs...

If you have a Connected Primary/Secondary UpToDate/UpToDate,
you crash, reboot, do whatever you want, to the Primary,
while the Secondary stays Secondary,
there will not be any data diversion,
and they are expected to connect and sync up
once they can see each other again,
whether you configure any drbd level fencing or not.
