  First, I attached my cluster.conf. When /etc/init.d/cman starts, 
returns an ok, but when I try to mount my gfs partition returns this error:

[root at haldir cluster]# service mountgfs start
Mounting GFS filesystems:  /sbin/mount.gfs: lock_dlm_join: gfs_controld 
join error: -22
/sbin/mount.gfs: error mounting lockproto lock_dlm
[root at haldir cluster]#

And of course any service couldn't start .... And clustat output is:

[root at haldir cluster]# clustat

P.D: mountgfs it is a simple script that mounts gfs partitions because 
gfs script provided by redhat doesn't works with _netdev param under fstab.
