There should be. Maybe set "loglevel=debug" in /etc/drbdmanaged.cfg

For the second thing: There I would need more information. The version
we ship and the one from proxmox are very different. In between these
versions the architecture of DM was changed. Just as an example: If you
have two nodes in your cluster and you started DM only on one node, it
will never start up successfully. Or if only a minority of your overall
nodes is operational, drbdmanage will refuse to start, as it waits for a
majority.

-) Try to get logging working.
-) Maybe start with a simple one-node cluster. Just to check if it works
in general. In that case startup is trivial and fast.
-) Make sure that the majority (or in a two node cluster both) nodes
have a running drbdmange ("drbdmanage startup"). In that particular
version actually make sure all nodes are up.
- Startup will take longer, look at the syslog where it writes who won
the leader election, to which nodes it has contact, ...
- Please start a new thread, I think this is not proxmox related, it is
related to the new version and the new architecture.
