How to close a site, so you won't receive jobs from the RBs.

If you want to stop the RB from sending you jobs (for example as you want to do some update on your CE), an atribute exists in the ldif Schema which is consulted by the RB to check the availability of your site. This page explains how to publish a closed status on your farm. It's about the information system.

The right place:

The attributes GlueCEStateStaus can take some values for which the RB will look. These attributes may be :

  • Queueing: the queue can accept job submission, but can't be served by the scheduler
  • Production: the queue can accept job submissions and is served by a scheduler
  • Closed: The queue can't accept job submission and can't be served by a scheduler
  • Draining: the queue can't accept job submission, but can be served by a scheduler

This attribute is published under the dn: GlueCEUniqueId=hostname... And such a dn exists for each queue.

Now we are going to change the value of this attribute.

Changes:

You'll have to edit the /opt/lcg/var/gip/lcg-info-generic.conf Find the line whith the right dn. If it doesn't allready exist, add the line :

GlueCEStateStatus: Closed for closing your site

else, you'll only have to change the value of this attribute. Be carefull to remove any space at the end of the line. Do this for each queue you have to change. You should find a dn for each of these queues.

Taking the changes:

The command: /opt/lcg/sbin/lcg-info-generic-config /opt/lcg/var/gip/lcg-info-generic.conf should do it.

Don't forget that, if you're using a BDII as GIIS, you have to wait until the BDII refreshes itself or refresh it manually.

If you want to remove the closed status of your site, simply remove the line you added or change the value at will.

How to set an schedule downtime:

Instructions in such a case are:

  • Set downtime period in GOC DB (link) and tick off "monitoring" for the affected nodes.
  • Announce the downtime through the EGEE broadcast tool to and only to all VO managers (link)
  • Change the status of your site to "closed" in the site Information System (GlueCEStateStatus: Closed).

To declare your downtime in the GOC DataBase, please go to https://goc.grid-support.ac.uk/gridsite/db/index.php
