In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
OCFS2 is a general purpose extent based shared disk cluster file
system with many similarities to ext3. It supports 64 bit inode
numbers, and has automatically extending metadata groups which may
also make it attractive for non-clustered use.

You'll want to install the ocfs2-tools package in order to at least
get "mount.ocfs2".
