RE: Can you help me on Linux SW RAID?

["J. Ryan Earl" <ryan@dynaconnections.com>]

OCFS2 isn't stable yet, I wouldn't suggest its use for production systems.
Furthermore, where did the requirement for 2.6 (kernel I assume) come from?
Sounds like he was using RHEL3 anyway...

I'm not familar with the 9i RAC setup, but I installed a 10g RAC that's in
production now.  The only thing I use OCFS for is Cluster Registry, Disk
Voting, and the Oracle Parameter File.  All database nodes have access to
the same set of raw LUNs on the SAN managed via ASM (Automated Storage
Management, a 10g feature) for keeping actual data on.  You could just put
all your Oracle files/data on OCFS, but that's not the highest performance
solution.

To have multiple nodes access a non-Oracle data on a clustered filesystem,
go with GFS for sure, ie a normal POSIX complaint filesystem.  OCFSv1 isn't
POSIX complaint and only properly stores Oracle specific files, and though
OCFSv2 is meant to be a generic clustered filesystem, it's not production
ready like I mentioned before: http://oss.oracle.com/projects/ocfs2/

How you setup the RAID is completely different issue from how you cluster
your data among nodes.

OCFS isn't available on 2.6. On 2.6, you have to use OCFS2.
