KFS(4)                     Kernel Interfaces Manual                     KFS(4)



NAME
       kfs - disk file system

SYNOPSIS
       disk/kfs [ -rc ] [ -b n ] [ -f file ] [ -n name ] [ -s ]

DESCRIPTION
       Kfs  is  a  local  user-level  file server for a Plan 9 terminal with a
       disk.  It maintains a hierarchical Plan 9 file system on the  disk  and
       offers 9P (see intro(5)) access to it.  Kfs begins by checking the file
       system for consistency, rebuilding the free list, and  placing  a  file
       descriptor  in /srv/name, where name is the service name (default kfs).
       If the file system is inconsistent, the user is asked for permission to
       ream (q.v.)  the disk.  The file system is not checked if it is reamed.

       The options are

       b n    If  the file system is reamed, use n byte blocks.  Larger blocks
              make the file system faster and less space efficient.  1024  and
              4096 are good choices.  N must be a multiple of 512.

       c      Do not check the file system.

       f file Use file as the disk.  The default is /dev/sd0fs.

       n name Use kfs.name as the name of the service.

       r      Ream the file system, erasing all of the old data and adding all
              blocks to the free list.

       s      Post file descriptor zero in /srv/service  and  read  and  write
              protocol messages on file descriptor one.

EXAMPLES
       Create  a  file  system  with  service  name  kfs.local and mount it on
       /n/kfs.

              % kfs -rb4096 -nlocal
              % mount -c /srv/kfs.local /n/kfs

FILES
       /dev/sd0fs
              Default file holding blocks.
