Hi all.
I have a cluster of 4 nodes:
- lb1.local, lb2.local: pound, varnish, memcache, nginx;
- storage1, storage2: no primitives/resources yet.
I want to set up an opt-in cluster
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.0/html/Pacemaker_Explained/ch06s02s02.html.
My config is:
node lb1.local
node lb2.local
node storage1
node storage2
primitive LBMemcached lsb:memcached \
meta target-role="Started"
primitive LBPound lsb:pound
primitive LBVIP ocf:heartbeat:IPaddr2 \
params ip="10.0.2.200" cidr_netmask="32" \
op monitor interval="30s" \
meta priority="100" target-role="Started" is-managed="true"
primitive LBVarnish lsb:varnish \
meta target-role="Started"
primitive MCVIP ocf:heartbeat:IPaddr2 \
params ip="192.168.100.200" cidr_netmask="32" \
op monitor interval="30s" \
meta target-role="Started"

The problem is that when I set
crm_attribute --attr-name symmetric-cluster --attr-value true
crm_mon:

As far as I can see I have proper priorities set for my
primitives/resources. Any clues?
Best regards,
