[Pacemaker] color_instance: Pre-allocation failed

[Stefan Midjich]

Every 15-18 minutes one of my resources gets stopped on one node and then
is restarted shortly after.

In the DC log I can see the following error lines.

Dec 28 15:04:09 app01 pengine: [8618]: debug: clone_rsc_colocation_rh:

This plays out before every stop event of OCFS.

Here is the cib.

I first suspected wrong network name resolution but /etc/hosts is correct
and no duplicate names.
