SYNOPSIS

DESCRIPTION

     -b block-size
                 The block size of the file system in bytes.

     -L          Create a log-structured file system (LFS).  This flag is cur-
                 rently required.

     -m free space %
                 The percentage of space reserved from normal users; the mini-
                 mum free space threshold.  The default value used is 10%.
                 See tunefs(8) for more details on how to set this option.
