Installing ocfs2 on Linux RedHat 4 update 3 (64 bit)

Question

OCFS2 being now certified on Linux RedHat 64 bit (since June second), we installed it on our Linux server.
Our kernel is:
$ rpm -qa | grep kernel
kernel-2.6.9-34.EL
kernel-smp-2.6.9-34.0.1.EL
kernel-smp-2.6.9-34.EL
kernel-utils-2.4-13.1.80
I got errors when trying to load ocfs2:
[root@db-red4-srv01 oracle]# /etc/init.d/o2cb status
Module "configfs": Not loaded
Filesystem "configfs": Not mounted
Module "ocfs2_nodemanager": Not loaded
Module "ocfs2_dlm": Not loaded
Module "ocfs2_dlmfs": Not loaded
Filesystem "ocfs2_dlmfs": Not mounted
[root@db-red4-srv01 oracle]# /etc/init.d/o2cb load
Loading module "configfs": Unable to load module "configfs"
Failed
[root@db-red4-srv01 oracle]# /etc/init.d/o2cb online ocfs2
Loading module "configfs": Unable to load module "configfs"
Failed
Also when trying to configure the nodes using ocfs2console, I get the following error:
#ocfs2console
-> cluster
-> configure nodes
Could not start cluster stack. This must be resolved
before any ocfs2 fileysystem can be mounted.
Anyone has an idea?
