Reproducible: Always Steps to Reproduce: 1. setup cluster 2. setup VirtualDomain resource configured as remote-node pcs resource create vm-guest01 VirtualDomain hypervisor=lxc:/// config=/root/lxc/lxc-01.xml force_stop=true meta remote-node=lxc-01 3. put some constraint e.g. location constraint: pcs constraint location vm-guest01 prefers reno-01 4. Try to delete VirtualDomain resource pcs resource delete vm-guest01 5. See error message Actual Results: pcs unable to delete the resource Expected Results: pcs delete the resource It happens always when parameter 'meta remote-node=<hostname>' is configured. In configuration without this parameter are resource and its constraint(s) deleted successfully.
