[ClusterLabs] [EXT] [EXT] pacemaker - Response 4 (part 1) to pid xyz failed

[lejeczek]

Well, did not think I should spam the list right away with 
the whole lot.
Should I show anything specific? Like I said, usual places, eg.:

-> $ pcs status --full

show nothing unusual, all the resources enabled are a ok, 
usual warnings:

-> $ pcs status --full | __grepColorIt 
'(error|fail|clone|pgsql)'

Cluster name: MINE

WARNINGS:
Following resources have been moved and their move 
constraints are still in place: 'box1.proxmox', 
'box2.proxmox', 'box3.proxmox', 'box4.proxmox', 
'box5.proxmox', 'box6.proxmox', 'esx1.vmware', 
'esx2.vmware', 'esx3.vmware', 'ocp0node', 'ocp1node', 
'ocp2node', 'podnode1', 'podnode2', 'podnode3', 'podster1', 
'podster2', 'podster3', 'ubusrv1', 'ubusrv2', 'ubusrv3'
Run 'pcs constraint location' or 'pcs resource clear 
<resource id>' to view or remove the constraints, respectively

Perhaps from from _pacemaker.log_ which I think might be 
"unusual" ?
