Doc Text: |
Pacemaker and ironic fought for control over power management, which caused issues with fencing. This fix sets force_power_state_during_sync=False in /etc/ironic/ironic.conf by default. This stops ironic automatically restoring the power state of the node during its synchronization. Pacemaker can now successfully fence the node.

The work around: 1.on the instack node edit /etc/ironic/ironic.conf file 2.Uncomment force_power_state_during_sync and set it to false. 3.restart openstack-ironic-conductor service. Lucas, can you make sure you default to having the force_power_state_during_sync to false and make sure there are docs describing how to turn it on if needed? @Chris, will do! @Leonid, that's not a workaround, that's the right way to do. Ironic by default will try to make sure that the machines are in sync with the database state. But we made it configurable for this kinda of situations. Btw, we don't have any fencing agent for Ironic in Peacemaker right? If Peacemaker used the Ironic interface to power on and off the nodes it's fencing this problem wouldn't happen. Lucas, a question on the gerrithub review about the use of tabs there. If that needs to be fixed, can you update the patch? once it's in shape, please submit to code.engineering as well. upstream and downstream patches merged ironic.conf includes force_power_state_during_sync=False instack-undercloud-2.1.2-21.el7ost.noarch Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
