We currently run ocfs2 1.4.x on RHEL 5, and we've been having huge problems. Our four-node cluster is simultaneously rebooting roughly once a week (sometimes more, sometimes less). The qlogic driver periodically rescans the fabric, and blocks IO while that happens. Sometimes it exceeds the ocfs2 tiemout, and cluster goes kaboom. We've increased the timeout values to absurd levels (more than a minute), and somehow it still happens.

So, my question is what other folks are doing for cluster storage on RHEL. We need the ability to share the database files as well as oracle software installs.
I know ASM is an option, but we haven't investigated it yet. I think is instance-specific, and thus can't be used for the oracle installed files? Other options might be GFS2 (Red Hat's cluster filesystem), Veritas, or something else entirely.
What are you folks using, and how do you like it?
