Created page with " == How to shut down the cluster == PageOutline === Kill all remaining jobs on the cluster and close the queues === Go to cream02 and issue <pre> ./kill_all_jobs ..."

New page

== How to shut down the cluster ==
[[PageOutline]]

=== Kill all remaining jobs on the cluster and close the queues ===
Go to cream02 and issue

<pre>
./kill_all_jobs
</pre>

Wait for all jobs to terminate. This will ensure that when one issues the shutdown of the worker nodes, there will be no lock on the /scratch<br>
To close the queues:

<pre>
cd
./disable_queues
</pre>

=== Switch off the worker nodes ===
on ccq:
<pre>
cd distrib-scripts/
./distrib_exec_list node_list_all_wns "poweroff"
</pre>

verify that all the WN's are indeed in the file node_list_all_wns. This file should be kept up-to-date.

=== Switch off storage ===
still on ccq

<pre>
./distrib_exec_list list_all_storage "poweroff"
</pre>

Also verify the file list_all_storage for completeness.<br>
Next, you still need to switch off the disks of some of the storage machines. You need to be at the CC to do this.

=== Switch off some servers ===
This will shut down a few virtual servers that need a proper shutdown<br>
<pre>
./distrib_exec_list list_servers_proper_shutdown "poweroff"
</pre>

=== Switch off the rest of the machines ===
mainly the M machines
<pre>
./distrib_exec_list list_proper_shutdown_the_rest "poweroff"
</pre>
=== Last switch off ===

power off ccq

=== verify ===
verify that all is indeed off
