I have a 3 node vCloud Director cluster, running as 1 primary and 2 standby nodes.
The repmgr cluster show command returns results you would expect to see.
If I run the repmgr cluster matrix however, I see that the node cannot SSH to the other nodes and therefor returns unknown status for the other 2 nodes.
root@node3 [ ~ ]# sudo -i -u postgres /opt/vmware/vpostgres/10/bin/repmgr -f /opt/vmware/vpostgres/10/etc/repmgr.conf cluster show
