I'm testing stickiness in a sandbox that consists of 3 nodes. The
configuration is very simple but it's not acting the way I think it should.
My configuration:
# crm configure show
node hasb1
node hasb2
node hasb3
primitive postfix lsb:postfix \
op monitor interval="15s"
property $id="cib-bootstrap-options" \
dc-version="1.1.7-6.el6-148fccfd5985c5590cc601123c6c16e966b85d14" \
cluster-infrastructure="openais" \
expected-quorum-votes="3" \
no-quorum-policy="ignore" \
stonith-enabled="false" \
last-lrm-refresh="1349902760" \
maintenance-mode="false" \
is-managed-default="true"
rsc_defaults $id="rsc-options" \
resource-stickiness="100"
The test resource "postfix" lives on hasb1.
# crm_simulate -sL
Current cluster status:
Online: [ hasb1 hasb3 hasb2 ]
postfix (lsb:postfix): Started hasb1
Allocation scores:
native_color: postfix allocation score on hasb1: 100
native_color: postfix allocation score on hasb2: 0
native_color: postfix allocation score on hasb3: 0
On hasb1 I'll kill the corosync process. Resource moves over to hasb2 as
expected.

Now I'll start corosync & pacemaker. Postfix resource moves back to hasb1
even though we have default stickiness.

What am I missing? I'm pulling my hair - any help would be appreciated
greatly.
Corosync 1.4.1
Pacemaker 1.1.7
