location constraints are somehow not honored by pacemaker 1.1.10 on el6.
I have an IP adress which is placed first and then a volumegroup and a
filesystem which choose the same node. The IP should be placed on x432, but
for some reason it chooses x430. There are additional resources running
(also choosing strange nodes).
the resource (pcs status):
ip_x43c (ocf::heartbeat:IPaddr2): Started x430
the constraint (pcs constraint)
Resource: x43c
Enabled on: x432 (score:10001)
Cluster properties (pcs property)
cluster-infrastructure: cman
cluster-recheck-interval: 60s
default-resource-stickiness: 10
maintenance-mode: false
symmetric-cluster: true
checking the scoring vim crm_simulate -sL i get
native_color: ip_x43c allocation score on x430: 30
native_color: ip_x43c allocation score on x431: 0
native_color: ip_x43c allocation score on x432: -INFINITY
the score of 30 on x430 is ok. There is a resourcegroup with two resource
with a colocation on the ip. But i can't figure out why x432 get's
-INFINITY, there is no further constraint regarding any of the resources in
question. I expect them to migrate to x432 after 60 seconds, but nothing
happens.
I trieds stopping vgfs_service_c, the ip remains. i stopped the ip. Started
it again, comes up on x430 again.
