[Linux-cluster] rgmanager fails to start!

[push mail]

Hi,

I have four nodes in a clustering.

Cman is working correctly in all nodes, but rgmanager works only in one node
(server4) ! trying to start rgmanager on the others nodes fails!

clurgmgrd concludes that locks are not working and exists.

following cluster.conf file and output

[root at server1 ~]# uname -a
Linux server1 2.6.18-53.1.14.el5 #1 SMP Wed Mar 5 11:36:49 EST 2008 i686

[root at server1 ~]# rpm -q cman
cman-2.0.60-1.el5

[root at server1 ~]# rpm -q rgmanager
