Hi all,
I've setup a simple two node cluster, and did some testing on it, but I'm
having problems interpreting the results. Unfortunately I couldn't find any
documentation answering my questions, so I'll post them here.
I don't want to do any complicated stuff, just run CLVM properly to serve
logical volumes as iSCSI targets. The iSCSI target software should run on both
nodes, independent of the cluster stack. The cluster is needed only because of
CLVM. I tried to avoid using fencing as much as possible since I don't really
see the need for it. My cluster.conf looks like this:
<cluster name="iscsigw" config_version="5">
<cman two_node="2" expected_votes="1" />
<clusternodes>
<clusternode name="iscsigw1" nodeid="1">
<fence />
<unfence />
</clusternode>
<clusternode name="iscsigw2" nodeid="2">
<fence />
<unfence />
</clusternode>
</clusternodes>
<fencedevices />
<rm />
</cluster>
To test things, I broke the connection between the nodes for a while, and then
restored it. I expected the cluster to return to normal state, but it didn't.
The main difference between the nodes is the "wait state", about what I could
hardly find any documentation. On one node it's "messages", on the other it's
"quorum". Could you explain what these mean and how to return the cluster into
normal state?
Thanks,
