Ok, I admit I don't know a lot about the subject, but isnt the linux
clustering system gfs or something like that alsoe usable? And wouldn't
that be a free filesystem?

Actually, OCFS is the only "free" filesystem you can use for RAC. You
can also use Veritas software and HP (formerly Polyserve) software to
provide a certified cluster filesystem on Linux. And, before Kevin adds
it, you can also use NFS. :)

ASM might be a good fit for you.
The only filesystem you can use for RAC on linux is OCFS. I've setup
clusters with the OCR and quorum on both filesystems and raw devices and
to me the only difference is what you're more comfortable with.

I need RAC expert's comments for the following questions.
1) What type of filesystem are you using for Oracle datafiles?
2) Are your implementation(s) using raw partitions or a cluster file
system for the OCR and voting disks?
3) If using raw partitions with Linux can you describe any challenges
you had with device discovery?
Thanks,
Rama
