NAME

       sload.f2fs - load directories and files into the device directly

SYNOPSIS

       sload.f2fs  [  -f source-directory-path ] [ -t mount-point ] [ -d debugging-level ] [ -P ] [ -c [ -L log-
       of-blocks-per-cluster ] [ -a compression-algorithm ] [ -x file-extension-to-exclude-from-compression | -i
       file-extension-to-include-for-compression ] [ -m minimum-compressed-blocks-per-cluster ] [ -r ] ] device

DESCRIPTION

       sload.f2fs is used to load directories and files into a disk partition, or an F2FS image (file).   device
       could a special file corresponding to the device (e.g.  /dev/sdXX), or an F2FS image file.

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

OPTIONS

       -f source-directory-path
              Specify the source directory path to be loaded.

       -t mount-point-path
              Specify the mount point path in the partition to load.

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

       -P     Preserve owner: user and group.  The user and group  of  the  source  files  will  be  taken  into
              account.

       -c     Enable  a  cluster-based  file  compression.   The  file  would be chopped into clusters, and each
              cluster is compressed independently.

       -L log-of-blocks-per-cluster
              Specify cluster size in power of two blocks.  The minimum value is 2  (4  blocks,  default).   The
              maximum value is 8 (256 blocks).  Note that a block contains 4096 bytes.  This option must be used
              with option -c.

       -a compression-algorithm
              Choose the algorithm for compression. Available options are: lzo, lz4 (default).  This option must
              be used with option -c.

       -i file-extension-to-include-for-compression
              Specify a file extension to include for the compression.  To specify multiple file extensions, use
              multiple  option -i's.  Files having one of the listed extensions will be compressed.  This option
              must be used with option -c.

       -x file-extension-to-exclude-from-compression
              Specify a file extension to exclude from compression.  To specify multiple  file  extensions,  use
              multiple option -x's.  Files having one of the listed extensions won't be compressed.  This option
              must be used with option -c.

       -m minimum-compressed-blocks-per-cluster
              Specify  a  minimum  block  count  saved  (by  compression)  per  cluster.  The minimum value is 1
              (default).  Maximum value is the cluster size in blocks minus 1.   If  compression  of  a  cluster
              fails  to  save  at least the minimum compressed block count given by the option, the cluster will
              not be compressed.  This option must be used with option -c.

       -r     Specify read-only flag for the compressed files.  It allows filesystem to release compressed space
              to the users, since, without this option,  filesystem  should  keep  the  space  for  future  file
              updates.  This option must be used with option -c.

NOTES

       If  neither -i nor -x is used, all files will be compressed.  Obviously, option -i and -x can not be used
       together.
