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. :)
This list hasn't been updated for 11g yet, but there is some good stuff at http

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
