hi all

I would appreciate some help.

I have set up a cluster 3.0.3 with 2.6.31 kernel
All went well until I tried a gfs2 mount. The mount hangs without an error
gfs_control dump reports nothing:

gfs_control dump
1256941054 logging mode 3 syslog f 160 p 6 logfile p 6 
/var/log/cluster/gfs_controld.log
1256941054 gfs_controld 3.0.3 started
1256941054 /cluster/gfs_controld/@plock_ownership is 1

/var/log/cluster/gfs_controld.log
1256941054 group_mode 3 compat 0


an strace on mount comand it appers that gfs_control is not responding

any idee how to proceed further?

thank you

Reproducible: Always

Steps to Reproduce:
1. start the cluster

ulimit -c unlimited
modprobe dlm
modprobe gfs2
mount -t configfs none /sys/kernel/config

cman_tool join
fence_node -U
groupd
fenced
dlm_controld
gfs_controld
fence_tool join


2. try to mount a gfs2 partition

Actual Results:  
mount hangs and gfs_controld is not responding
