Description BugBuster666 2013-11-08 12:02:21 UTC

Description of problem:

After updating to the latest pacemaker / resource agents release on RHEL (CentOS), (https://rhn.redhat.com/errata/RHEA-2013-1494.html) we found that the "Delay" Resource Agent is missing from the package. Before it was part of the resource-agents package.

This missing resource agents leads to unexpected cluster behaviour after the update of pacemaker and resource-agents.

Version-Release number of selected component (if applicable):

resource-agents-3.9.2-21.el6_4.8

How reproducible:

Upgrade the resource-agents package from resource-agents-3.9.2-21.el6_4.3 to resource-agents-3.9.2-21.el6_4.8. See if "Delay" resource agents is part of the package. Delay resource agent is missing, while it was part of resource-agents version resource-agents-3.9.2-21.el6_4.3.

[root@SRV~]# LANG=C ls -al /usr/lib/ocf/resource.d/heartbeat/Delay
ls: cannot access /usr/lib/ocf/resource.d/heartbeat/Delay: No such file or directory

Steps to Reproduce:
1. install resource-agents-3.9.2-21.el6_4.3
2. verify /usr/lib/ocf/resource.d/heartbeat/Delay exists
3. upgrade resource-agents-3.9.2-21.el6_4.8
4. verify /usr/lib/ocf/resource.d/heartbeat/Delay missing

Actual results:

Resource agent /usr/lib/ocf/resource.d/heartbeat/Delay missing.

Expected results:

Resource agent /usr/lib/ocf/resource.d/heartbeat/Delay should be within the package, as during minor version upgrades no Resource Agents should be removed !! (this update is not even a real version inclease .. to much change within an enterprise distribution). Also the removal of the Agent was not listed in the errata (https://rhn.redhat.com/errata/RHEA-2013-1494.html).

Additional info:

Please add /usr/lib/ocf/resource.d/heartbeat/Delay to resource-agents again and provide an updates package.

Regards,
Robert

Delay is blind to whether or not the condition that is being waited on has completed or not.  This is generally not a recommended approach.

Can you describe your usage of Delay.  This agent was removed because we were unable to come up with a supportable use-case for the agent.

Thanks,

Comment 3 BugBuster666 2013-11-08 16:13:48 UTC

Hello, 

that's what Andrew B. also asked :)

Use case details here: 
  http://www.mail-archive.com/pacemaker@oss.clusterlabs.org/msg18189.html

We have a setup of load balancing via OSPF (ECMP). We must make sure that some service is stopped not before 30 seconds (or better OSPF heartbeat timeout) after the stop of the OSPF deamon (quagga). This allows seamless failover without any downtime.

- OSPF session active and traffic is routed to our load balancer
- crm node standby
- now OSPFD should be stopped
(now ~<OSPF dead detection timeout> seconds, traffic is still routed to our node, which we want to service, in our case ~10sec)
- we wait 30 seconds (with Delay)
(after ~<OSPF dead detection timeout> seconds, no more traffic to our "standby node")
- now the load balanced service should be stopped

For this we need Delay :)

Comment 4 David Vossel 2013-11-20 19:35:56 UTC

This only requires a spec file change that removes the excludes line associated with the Delay agent and its man page.

Comment 10 michal novacek 2014-07-24 08:19:34 UTC

I have verified that Delay resource agent is present in
resource-agents-3.9.5-11.el6.x86_64.

# rpm -q resource-agents
resource-agents-3.9.5-11.el6.x86_64

# ls -l /usr/lib/ocf/resource.d/heartbeat/Delay
