Hi Fabione,
Thanks for rolling this rc candidate!

We used these without any patches.

We were running against 2.6.30.

We observed these issues:

fenced segfaults with:

(gdb) bt
#0  0x00007f8e293508fe in fence_node (victim=0x114b510 "node1.foo.bar", log=0x61e0a0, log_size=32, log_count=0x7fff2e46a634) at /var/home/schmitz/3/redhat-cluster/fence/libfence/agent.c:156

this leads to

1246297857 fenced 3.0.0.rc3 started
1246297857 our_nodeid 1 our_name node2.foo.bar
1246297857 logging mode 3 syslog f 160 p 6 logfile p 6 /var/log/cluster/fenced.log
1246297857 found uncontrolled entry /sys/kernel/dlm/rgmanager

when trying to restart fenced. Since this is not possible one has to
reboot the node.

We're also seeing:

Jun 29 19:29:03 node2 kernel: [   50.149855] dlm: no local IP address has been set
Jun 29 19:29:03 node2 kernel: [   50.150035] dlm: cannot start dlm lowcomms -107

from time to time. Stopping/starting via cman's init script (as from the
Ubuntu package) several times makes this go away.

Any ideas what causes this?
Cheers,
