Hello Craig,
The current setup is two server which run libvirt and for storage which run glusterfs (storage server feed two virtual servers).  Right now is no fencing in place. Each of the nodes have one  PostgreSQL vm with bdr.

Hello Everyone,
I am looking for suggestion how to recover bdr replication.
The short story we have 2 virtual nodes with share storage.

Can you describe the "shared storage" setup in more detail?

In general, with PostgreSQL "shared storage" is a shortcut to "massive database corruption" unless you have extremely careful fencing and STONITH.
