So it's my understanding that you have to be on 11.2 Grid Infrastructure, correct?
We're getting to 11.2 GI but it is still sometime in the future.

I'm a bit wary of using a clustered filesystem built by a database company compared to a clustered filesystem technology built (or designed) by a group that focuses on filesystem technologies (though perhaps such a filesystem technology doesn't really exist).

I got burned using OCFS (performing a "routine" upgrade) many years ago and still don't like it as it seems less than awesome.

Yes, it is.  You can add space to ASM with the database up.  Also, you can run 11gr2 clusterware and ASM with a 10.2 database in which case you can use ACFS to store files in addition to the database files.

Nope, not yet.  And this is a 10.2.0.4 RAC system so is ASM filesystem applicable?

Have you used ASM?

I'm curious if anyone uses anything other than OCFS/OCFS2 filesystems for their RAC shared storage areas?
It seems that OCFS (our version anyway) is not extendable unless you take it offline.  A key point for me would be a clustered filesystem that is dynamically growable as needed.

Anyone have any thoughts on the matter?
