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 per-
       mission 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.
