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. :) <br>

ASM might be a good fit for you.<br>
<br>
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. <br>
