There are two ways
- Use PBS Pro inbuilt failover ( you would need two server(Primary & Secondary) and one storage server (with NFS , NFS lock enabled) on which PBS_HOME is mounted with file locking enabled. It active active configuration, if Primary fails, secondary finds it out and then starts its services using the shared $PBS_HOME directory (at any one point in time one of the servers is active and writing to PBS_HOME) - Failover Setup Issues - #2 by adarsh
- Integrate with external High Availability solutions
Hope this helps.
