I was not blinding following RHEL4 doc which is why i did not look for installing those packages once after i did "Cluster" and "ClusterStorage" group install assuming everything must be there.
I started having a doubt about any missing packages because of those dlm errors reported in the messages i sent earlier.
Aug 23 05:02:59 server1 dlm_controld[27892]: group_init error (nil) 111
Aug 23 05:02:59 server1 fenced[27886]: group_init error (nil) 111
Searching on some forums always gives me old replies about RHEL4 and error which talks about some dlm rpm's, thats why.

I haven't used the rhcs stable 2 (version in RHEL 5) in some time, and I
don't remember for sure. I don't think I've seen magma though.
Why are you following the docs for RHEL 4, installing on RHEL 5 when
RHEL 6 is the current version?
