RedHat 5.8: FATAL: Module lock_dlm not found. [FAILED]

You are trying to start cman, but you got this erro:

[root@ora1 ~]# service cman start
Starting cluster: 
   Loading modules... failed
FATAL: Module lock_dlm not found.
                                                           [FAILED]

 

Does Oracle provide support for Red Hat Global File System (GFS), Red Hat Cluster Suite (RHCS), or RedHat Application Server (RHAS)?

Red Hat Global File System (GFS) and Red Hat Cluster Suite (RHCS) are part of RHEL5 and Oracle Linux 5 so they are supported by Oracle under the Linux Support Program.

However, since GFS and RHCS are not included with RHEL4, Oracle Linux 4 and earlier versions, they are not supported by Oracle with RHEL4, OL4, and earlier versions.

Similarly, Oracle Linux 6 does not include support for features that are delivered as extra cost add-ons in Red Hat Enterprise Linux 6, such as the High Availability Add-On for clustering and the Resilient Storage Add-On for GFS2.

 

Look module lock_dlm inside the /etc/init.d/cman:

[root@ora1 ~]# uname -r
2.6.32-300.32.1.el5uek
[root@ora1 ~]# grep lock_dlm /etc/init.d/cman
    errmsg=$( /sbin/modprobe lock_dlm 2>&1 ) || return 1

Comment that line:

[root@ora1 ~]# vi /etc/init.d/cman
[root@ora1 ~]# grep lock_dlm /etc/init.d/cman
#    errmsg=$( /sbin/modprobe lock_dlm 2>&1 ) || return 1

Try to start cman again:

[root@ora1 ~]# /etc/init.d/cman start
Starting cluster: 
   Loading modules... done
   Mounting configfs... done
   Starting ccsd... done
   Starting cman... done
   Starting daemons... done
   Starting fencing... done
                                                           [  OK  ]
[root@ora1 ~]#
