[Linux-cluster] Why does GFS2 freeze?

[Vladimir Melnik]

Dear colleagues,

Thank you all for all your yesterday's help. Alas, I had to reboot both
nodes about 5am, because the situation has gone critical.

Now I built almost the same cluster in a lab. Its configuration is REALLY
simple:

<?xml version="1.0"?>
<cluster name="cluster1" config_version="1">
  <cman two_node="1" expected_votes="1"/>
  <clusternodes>
    <clusternode name="vlan201.eth0.host1.lab.***.net" votes="1"
nodeid="1"/>
    <clusternode name="vlan201.eth0.host2.lab.***.net" votes="1"
nodeid="2"/>
  </clusternodes>
  <fencedevices/>
  <rm>
    <failoverdomains/>
    <resources/>
  </rm>
</cluster>

I started iscsi, cman, clvmd, gfs2 and rgmanager. When I'm disconnecting a
node, the second node can't work with the same filesystem: any attempt to
open some file just waits. But when I'm reconnecting the node back, files
are opening and all is working.

I'm sorry if it's a noob's question, but why does it ignore "<cman
two_node="1" expected_votes="1"/>"?

Thank you!
