RestartQueue

Restarting grape's queue

If you see this error:

[root@grape ~]# showq ERROR: cannot send request to server grape:42559 (server may not be running) ERROR: cannot request service (status)

it means the queue server is down. The queue can be restarted by running as root just two commands:

[root@grape ~]# /etc/init.d/pbs restart Password:Restarting PBS Shutting down PBS: Stopping pbs_server: [ OK ] Stopping maui: [FAILED] Starting PBS daemons: Starting pbs_server: [ OK ] Starting maui scheduler: [ OK ] done.

This will restart the queue. Then to release the hold on jobs that were Blocked (Deferred because the queue was unavailable), run as root:

[root@grape ~]# showq | grep Deferred | awk '{print $1}' | xargs -n 1 releasehold
