	  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".

	  Note: Features which OCFS2 does not support yet:

	          - extended attributes

	          - readonly mount

		  - shared writeable mmap

	          - loopback is supported, but data written will not

	            be cluster coherent.

	          - quotas

	          - cluster aware flock

	          - Directory change notification (F_NOTIFY)

	          - Distributed Caching (F_SETLEASE/F_GETLEASE/break_lease)

	          - POSIX ACLs

	          - readpages / writepages (not user visible)
