       mkfs.f2fs - create an F2FS file system

       mkfs.f2fs  [  -a heap-based-allocation ] [ -l volume-label ] [ -o over‐
       provision-ratio-percentage ] [ -s log-based-#-of-segments-per-section ]

       mkfs.f2fs is used to create a f2fs file system (usually in a disk  par‐
       tition).	  device is the special file corresponding to the device (e.g.

       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. The default percentage is 5%.

       -s log-based-#-of-segments-per-section
	      Specify  the log-based number of segments per section. A section
	      consists of multiple consecutive segments, and is	 the  unit  of
	      garbage  collection.   The  default number is 0, 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 mul‐
	      tiple  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 mul‐
	      timedia 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.
