The Oracle Cluster File System (OCFS, in its second version OCFS2) is a
shared disk file system developed by Oracle Corporation and released under the GNU General Public License
.
The first version of OCFS was developed with the main focus to accommodate Oracle's cluster computing. Because of that it was not a POSIX
-compliant file system. With version 2 the POSIX features were included.
OCFS2 (version 2) was integrated into the version 2.6.16 of
OCFS2 used a distributed lock manager which resembles the OpenVMS DLM but is much simpler.[4] Oracle announced version 1.6 in November 2010 which included a
copy on write feature called reflink.[5]
