SolutionYou can use RAW devices or OCFS2.
>>>what about OCFS2 ? is it equivalent/better then Redhat's GFS ?
OCFS2 would be equivalent than Red Hat GFS. Please see:
www.oracle.com/technologies/linux/ubl-faq.pdf
"Red Hat Global File System (GFS) and Red Hat Cluster Suite (RHCS) are part of RHEL5 and OEL5 so they are supported by Oracle under the Unbreakable Linux Program. However, since GFS and RHCS are not included with RHEL4, OEL4 and earlier versions, they are not supported by Oracle with RHEL4, OEL4, and earlier versions."
Redhat's GFS competetor ?

Re: Redhat's Global Filesystem
Serviceguard does not provide a filesystem. Serviceguard is a clustering package that permits the high availability setup and package failover.
GFS is a cluster enabled filesystem that is designed to work with Red Hat Cluster Suite, which does provide roughly the same functionality of Servicdguard.

Re: Redhat's Global Filesystem
>You can use RAW devices ...
A High Availability Cluster of almost 7 Database Servers using SAN of RAW devices.. does it make sense.. or does it worthed ? Ivan this is simply a question(my english is not good, might be I used hard words)
I mean, i think its almost necessary to use a cluster aware filesystem for the storage on SAN, as these storage devices are shared among multiple Servers.
I need help, in this regard to make the decisions.
Any one has experiene of using OCFS and/or Redhats' GFS ? which one is more reliable/stable ?
Thanks n Regards
Maaz

I know peple using OCFS without any problems. We use GFS and works without problems also. In this case, I think that the desition is up to you.

However (and I'm no expert here, I've just read a few bits) one of the advantages of OCFS2 is it's ability to support various block sizes without relying on the same buffering that presents limitations to efficiency in Linux filesystems. This is particularly effective for datawarehousing applications where larger block sizes are advantageous.
If you need me to I can see if I can dig up the docs I have or the links I found....
