Description Radek Steiger 2016-10-29 18:24:37 UTC 
> Description of problem:

Removing booth resource and its IPaddr2 sibling with 'pcs remove commands' fails when the group is disabled, leaving the IP resource in place and removing the booth-site instance only. This however doesn't happen when the group as such is enabled, but any of the resources is either disabled or stopped.

[root@virt-019 ~]# pcs status
...
 Resource Group: booth-booth-group
     booth-booth-ip	(ocf::heartbeat:IPaddr2):	Started virt-029.cluster-qe.lab.eng.brq.redhat.com
     booth-booth-service	(ocf::pacemaker:booth-site):	Started virt-029.cluster-qe.lab.eng.brq.redhat.com

1. pcs resource disable booth-booth-group

Fixed crash when the group's meta_attributes are placed before the group's resources in the CIB. See the test included in the patch for details.
