 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.
-This spell provides tools for creating, checking, mounting and tuning OCFS2 file-
-systems.
