Pacemaker/corosync timeout before resource transfers

  • 772

This seems like a simple question, but one I can't seem to find the answer for despite going over the pacemaker documentation multiple times.

I've got corosync set up with pacemaker to share a virtual IP. All I want to do is to set a timeout value before the backup node takes over the resource. With network outages of <1-2 minutes I'd like pacemaker to just continue on as normal instead of triggering failover, but switch it over if the outage is over a certain number.

There is a timeout for a resource - but this seems to be a the timeout waiting for the resource to start, not for the cluster as a whole.

  1. It sounds like migration-threshold is what you're looking for.

    Assumming that you have a resource which is setting op monitor interval to 20s:

    primitive p_foo ocf:heartbeat:foo \
    params ...
    op monitor interval="20s"

    and you want it doesn't migrate to a new node within 1 minute, so you should set migration-threshold to 3:

    primitive p_foo ocf:heartbeat:foo \
    params ...
    op monitor interval="20s"
    meta target-role="Started" migration-threshold="3"
