SYNOPSIS

       mkfs.f2fs  [  -a  heap-based-allocation  ] [ -l volume-label ] [ -o overprovision-ratio-percentage ] [ -s

       device [sectors]

DESCRIPTION

       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.

OPTIONS

       -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.
