did the cluster ever work? or did creating a cluster not work initially?
any information in the logs?
else you can try to recreate the cluster:
* make a backup of both machines
* recreate the cluster:
** remove /etc/pmg/cluster.conf on both nodes
** create the cluster again
** capture any problem you encounter while creating the cluster
the problem with the creation phase is due to the moment in which all the machines have a firewall in front and they are on different clusters which ports I have to open for the cluster besides the 8006 and 22
please post the output of `pmgcm status` from both nodes and the journal for pmgmirror for both nodes (`journalctl -u pmgmirror`)
and verify that /etc/pmg/cluster.conf is the same on both nodes (keep in mind that it contains sensitive information)
