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.
