Default mount.gfs2 hangs on cluster-3.0.3

hi all

I would really 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

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

Need to find out what gfs_controld is doing:
gfs_control dump
strace and/or gdb on gfs_controld

neither strace or dump gives me nothing. the mount is stuck on that read and
gfs_controld reports nothing

thank you for you time
