OCFS (Oracle Cluster File System) is a shared disk file system developed by Oracle Corporation and released under the GNU General Public License. OCFS2 (version 2) was integrated into the version 2.6.16 of Linux kernel. Initially, it was marked as "experimental" (Alpha-test) code. This restriction was removed in Linux version 2.6.19. With kernel version 2.6.29 more features have been included into ocfs2 especially access control lists and quota.
