[ClusterLabs] Dependency loop

[George Kourvoulis]

Hi,

my logs keep being flooded by "Breaking dependency loop at <rsc_name>" but
I cannot figure out why. I haven't spotted such a loop.

redhat-release CENTOS 7.2.1511
pcs --version 0.9.143

Here's an excerpt from the logs:

Here's my pcs cluster cib output:

I am afraid that this could be the cause of my resources falling back to a
node that has recovered from a fail over although I have a stickiness score
of INFINITY.

Thanks,
George
