This says that DRBD is not talking to it's peer (StandAlone, you want
Connected) and that neither node is in Primary state (Secondary can not
be even looked at, by design).

Further, both think that they are UpToDate and that the other is
Unknown. This means you've gotten a split-brain and you will need to
recover by telling DRBD which node's data you want to keep and which
node's data you want to overwrite. This can be avoided with fencing (aka
"stonith"), which you must use when you have shared storage.
