       mkfs.f2fs - create an F2FS file system


       mkfs.f2fs  [  -a  heap-based-allocation  ]  [  -l volume-label ] [ -o overprovision-ratio-
       percentage ]  [  -s  #-of-segments-per-section  ]  [  -z  #-of-sections-per-zone  ]  [  -e
       extenstion-list ] [ -d debugging-level ] device [sectors]


       mkfs.f2fs  is  used to create a f2fs file system (usually in a disk partition).  device is
       the special file corresponding to the device (e.g.   /dev/sdXX).   sectors  is  optionally
       given for specifing the filesystem size.

       The exit code returned by mkfs.f2fs is 0 on success and 1 on failure.


       -a heap-based-allocation
              Specify  1 or 0 to enable/disable heap based block allocation policy.  If the value
              is equal to 1, each of active log areas are initially assigned separately according
              to the whole volume size.  The default value is 1.

       -l volume-label
              Specify the volume label to the partition mounted as F2FS.

       -o overprovision-ratio-percentage
              Specify  the  percentage  over the volume size for overprovision area. This area is
              hidden to users, and utilized by F2FS cleaner. If not specified,  the  best  number
              will be assigned automatically accoring to the partition size.

       -s #-of-segments-per-section
              Specify  the  number  of  segments  per  section.  A  section  consists of multiple
              consecutive segments, and is the unit of garbage collection.  The default number is
              1, which means one segment is assigned to a section.

       -z #-of-sections-per-zone
              Specify  the  number  of  sections  per zone. A zone consists of multiple sections.
              F2FS allocates segments for active logs with separated zones as much  as  possible.
              The default number is 1, which means a zone consists of one section.

       -e extension-list
              Specify  a file extension list in order f2fs to treat them as cold files.  The data
              of files having those extensions will be stored to the cold log.  The default  list
              includes most of multimedia file extensions such as jpg, gif, mpeg, mkv, and so on.

       -d debug-level
              Specify the level of debugging options.  The default number is 0, which shows basic
              debugging messages.
