Hi,
i have a Problem running a Two-Node Cluster (without qudisk) on RHEL 5.3
with all the latest Patches installed. For testing i use a very simple
setup with only one ip-address as the service.
Both nodes have two network-interfaces, both are configured in cluster.conf
<clusternodes>
<clusternode name="10.102.10.51" nodeid="1" votes="1">
<altname name="10.209.170.51"/>
<fence>
<method name="1">
<device name="ipsdb01.drac"/>
</method>
</fence>
</clusternode>
<clusternode name="10.102.10.28" nodeid="2" votes="1">
<altname name="10.209.170.28"/>
<fence>
<method name="1">
<device name="ips08.drac"/>
</method>
</fence>
</clusternode>
When the service runs on node b and i take down the first interface
(10.209.170.28) with: 'ip link set eth1 down' the service is taken over
by node a within a few seconds. When i then disable the second interface
on node b i would expect that node a recognize the failure and fence
down node b but this does not happen. This only occurs in this one
direction, the other way - node a holds the service and need to be
fenced by node b works fine.
What could cause such a behaviour ?
Here are some more sniplets which could be interessting from my cluster.conf
<fence_daemon clean_start="1" post_fail_delay="10" post_join_delay="30"/>
<cman expected_votes="1" two_node="1">
Most of the configuration was done using conga (luci,ricci)
Regards
Marco
