Hey,
I'm currently trying latest pacemaker RPM on Fedora rawhide together
with cman/OpenAIS:
cman-3.0.16-1.fc15.i686
openais-1.1.4-1.fc15.i686
pacemaker-1.1.2-7.fc13.i386 (rebuild from rhel6 beta)
I have a very basic cluster.conf (only for testing):
# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster name="iscsicluster" config_version="2">
<cman two_node="1" expected_votes="1"/>
<clusternodes>
<clusternode name="iscsi1" votes="1" nodeid="1">
<fence>
<method name="1">
<device name="manual"
nodename="iscsi1"/>
</method>
</fence>
</clusternode>
<clusternode name="iscsi2" votes="1" nodeid="2">
<fence>
<method name="1">
<device name="manual" nodename="iscsi2"/>
</method>
</fence>
</clusternode>
</clusternodes>
<fencedevices>
<fencedevice agent="fence_manual" name="manual"/>
</fencedevices>
<rm/>
</cluster>
pacemaker config looks like this:
# crm configure show
node iscsi1
node iscsi2
primitive drbd_disk ocf:linbit:drbd \
params drbd_resource="virt_machines" \
op monitor interval="15s"
primitive ip_drbd ocf:heartbeat:IPaddr2 \
params ip="192.168.122.100" cidr_netmask="24" \
op monitor interval="10s"
primitive iscsi_lsb lsb:tgtd \
op monitor interval="10s"
group rg_iscsi iscsi_lsb ip_drbd \

rule $id="cli-prefer-rule-rg_iscsi" inf: #uname eq iscsi2
colocation c_iscsi_on_drbd inf: rg_iscsi ms_drbd_disk:Master
order o_drbd_before_iscsi inf: ms_drbd_disk:promote rg_iscsi:start
property $id="cib-bootstrap-options" \
dc-version="1.1.2-f059ec7ced7a86f18e5490b67ebf4a0b963bccfe" \
cluster-infrastructure="cman" \
stonith-enabled="false" \
no-quorum-policy="ignore"
this works fine so far:
# crm_mon

for testing no fence device is configured. using fence_ack_manual to
confirm node shutdown, but that's exactly the problem. when I switch off
iscsi1, no resource failover happened after I called fence_ack_manual:
/var/log/messages:
Sep 15 18:09:02 iscsi2 fenced[1171]: fence iscsi1 failed

Wondering why no service failover happened after I manually confirmed
the shutdown of the first node with fence_ack_manual.
maybe someone knows what's going on?!
Cheers,
Thorsten
