[Pacemaker] master/slave problems

[Sam Pinar]

Hi,

I've setup a two node cluster for testing using the "Clusters from Scratch -
Apache, DRBD and GFS2" guide. I've set it up and fail over works like a
charm, but I want one of the nodes to be a master; and fail back resources
to the master when it comes back up. At the moment, the resource stays at
the failed back node. configs:


node ULTPLN30.DMZ
node ULTPLN31.DMZ \
        attributes standby="off"
primitive ClusterIP ocf:heartbeat:IPaddr2 \
        params ip="10.110.4.123" cidr_netmask="32" \
        op monitor interval="30s"
property $id="cib-bootstrap-options" \
        dc-version="1.1.5-1.1.el5-01e86afaaa6d4a8c4836f68df80ababd6ca3902f"
\
        cluster-infrastructure="openais" \
        expected-quorum-votes="2" \
        stonith-enabled="false" \
        no-quorum-policy="ignore"
