[Drbd-dev] Integrating iSCSI service to DRBD for iSCSI failover - Heartbeat

[sajan agr]

Hi

I am a naive user of pacemaker and have been trying to achieve iSCSI
failover on Pacemaker. I have tried couple of things though, which logically
looks fine. But, I am not able to get any progress in this. So, I wanted to
share this problem with you and help me sort out the problem.

This is how my CIB file looks like :

node $id="1c96735b-59c8-47d9-a2c6-cd2a2731d936" drbd_desk1 \
        attributes standby="off"
node $id="b8c4fa16-df49-45b7-a850-cb9f65af036e" drbd_desk2 \
        attributes standby="off"
primitive drbd_test ocf:linbit:drbd \
        params drbd_resource="r0" \
        op monitor interval="15s" \
        meta target-role="started"
primitive ip_drbd ocf:heartbeat:IPaddr2 \
        params ip="192.168.30.33" nic="eth0" \
        meta target-role="started"
primitive iscsiLU ocf:heartbeat:iSCSILogicalUnit \
        params lun="0" path="/dev/drbd0"
target_iqn="iqn.2009-10.com.systems:Testme" \
        meta target-role="started"
primitive iscsiTG ocf:heartbeat:iSCSITarget \
        params iqn="iqn.2009-10.com.systems:Testme" tid="1" \
        meta target-role="started"
group drbd_group ip_drbd iscsiTG iscsiLU
ms ms_DRBD drbd_test \
        meta master-max="1" master-node-max="1" clone-max="2"
clone-node-max="1" notify="true"
property $id="cib-bootstrap-options" \
        dc-version="1.0.5-462f1569a43740667daf7b0f6b521742e9eb8fa7" \
        cluster-infrastructure="openais" \
        no-quorum-policy="ignore" \
        stonith-enabled="false" \
        default-resource-stickiness="1000" \
        expected-quorum-votes="2" \
        last-lrm-refresh="1256633765"


crm_mon shows perfectly fine when both the nodes are up and shows all
services are running.

I powered off the master (desk2 at present), desk1 becomes master fine, but
the iscsiLU resource is seen 'Stopped' at this machine. I think this service
is not migrated here.

Can anyone guide me through this ?
