> *Scenario*
> # Start live backup server pair in dedicated topology with shared store HA,
> with journal located on NFS
> # NFS mounted on backup server fails
> # Reconnect NFS on backup server
> # Try to shut down live EAP server
> # Backup doesn't activate
> *What happens*
> Backup is waiting for live to fail by checking its file lock. In case the
> connection to shared storage fails, backup logs following error.

> Exception is caught in {{SharedStoreBackupActivation.run}}, and causes
> termination of backup activation process.
> In case the NFS is reconnected later, backup server doesn't continue in
> activation process and it doesn't wait for live to fail. In case the live
> fails, backup doesn't activate, even though it has a connection to shared
> storage.
> Backup should retry checking live lock even in case the storage is
> unavailable. It should log warning/error messages that storage is
> unavailable, but it should not terminate the activation process. This would
> allow backup to continue its duties when the storage is reconnected.
