[Linux-cluster] Why does GFS2 freeze?

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!
