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.

       -c device
              Build f2fs with this device additionally, so that user can see all the devices as one big volume.

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

       -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.

       -f     Force overwrite when an existing filesystem is detected on the device.  By default, mkfs.f2fs will
              not write to the device if it suspects that there is a filesystem or partition table on the device
              already.

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

       -m     Specify f2fs filesystem to supports the block zoned feature.  Without  it,  the  filesystem  isn't
              supports the feature.

       -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.

       -O feature-list
              Specify a feature list in order f2fs filesystem will supports.  e.g "encrypt" and so on.

       -q     Quiet mode.  With it, mkfs.f2fs does not show any messages include the basic messages.

       -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.

       -t nodiscard/discard
              Specify  1  or  0 to enable/disable discard policy.  If the value is equal to 1, discard policy is
              enabled, otherwise is disable.  The default value is 1.

       -wsector-size
              Specify the sector size in bytes along with given target sectors.  Without it, the sectors will be
              calculated by device sector size.

       -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.
