       mount.ocfs2 -  mount an OCFS2 filesystem


       mount.ocfs2 [-vn] [-o options] device dir


       mount.ocfs2  mounts  an  OCFS2 filesystem at dir. It is usually invoked
       indirectly by the mount(8) command when using the -t ocfs2 option.


              The filesystem resides on a device that requires network  access
              (used  to  prevent  the  system  from  attempting to mount these
              filesystems until the network has been enabled on  the  system).
              mount.ocfs2  transparently  appends  this  option  during mount.
              However,  users  mounting  the  volume   via   /etc/fstab   must
              explicitly  specify  this  mount option to delay the system from
              mounting the volume until after the network has been enabled.

              The file system will not update  atime  unless  this  number  of
              seconds  has passed since the last update. Set to zero to always
              update atime. It defaults to 60 secs.

              The file system only update atime if the previous atime is older
              than mtime or ctime.

              The file system will not update access time.

       acl    Enables POSIX ACLs(Access Control Lists) support.

       user_xattr / nouser_xattr
              Enables / disable Extended User Attributes.

              Sync  all  data  and  metadata  every nrsec seconds. The default
              value is 5 seconds.  Zero means default.

       data=ordered / data=writeback
              Specifies the handling of file data during metadata journalling.

                          This  is  the  default  mode.  All  data  is  forced
                          directly out to the main file system  prior  to  its
                          metadata being committed to the journal.

                          Data   ordering  is  not  preserved  -  data  may be
                          written into the main file system after its metadata
                          has  been  committed to the journal. This is rumored
                          to  be  the  highest-throughput  option.  While   it
                          guarantees  internal  file  system integrity, it can
                          allow old data to appear in files after a crash  and
                          journal recovery.

              Use  this  mount option to mount volumes storing the Oracle data
              files, control files, redo  logs,  archive  logs,  voting  disk,
              cluster  registry,  etc.   (This  mount option is only available
              with OCFS2 1.2 and OCFS2 1.4.)

       errors=remount-ro / errors=panic
              Define the  behavior  when  an  error  is  encountered.  (Either
              remount  the  file  system  read-only,  or  panic  and  halt the
              system.) By default, the file system is remounted read only.

              This disables cluster-aware flock(2).

       intr / nointr
              The default is intr that allows  signals  to  interrupt  cluster
              operations.   nointr disables signals during cluster operations.

       ro     Mount the file system read-only.

       rw     Mount the file system read-write.
