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.
