There is no logging happening in /var/run/cluster/
[root@server1 ~]# ls /var/run/cluster/
apache ccsd.pid ccsd.sock rgmanager.sk
I started resource manager in foreground and it says like ..
failed acquiring lockspace: No such device
Locks not working!
What next i could do ?

It is strange that strace shows that /var/run/cluster/rgmanager.sk is missing.
Normally it is helpful to see the complete cluster.conf. Could you provide that one?
Also of interest is /var/log/cluster/rgmanager.log - do you have debug enabled inside cluster.conf?
Maybe it is possible to start rgmanager in the foreground (-f) with strace? That might also be a way to show why the rgmanager.sk is missing ...
Just some ideas ...
Kind regards,
Heiko

I am trying to setup a simple two node cluster in my laptop using two RHEL VM's.
Everything looks just fine to me but i am unable to enable a apache service though it works beautifully when tried with "rg_test test" on both the nodes.
What could be the problem ? Please help. I am a novice in red hat cluster but learnt a bit of it in the last few days while trying to fix all the problems encountered.
Here are the details.

Please let me know if you can help. One thing i noticed was that in the "clustat" it does not show "rgmanager" against both the nodes but i see the service is just running fine.

Hope i have given all the details required to help me quickly. Thanks.
