PROGRAM:
NAME
9mount, 9bind, 9umount - mount/unmount 9p filesystems
SYNOPSIS
9mount [ insuvx ] [ -a SPEC ] [ -c CACHE ] [ -d DEBUG ] [ -m MSIZE ] DIAL MOUNTPT
9bind OLD NEW
9umount MOUNTPT
DESCRIPTION
9mount mounts a 9p filesystem served at DIAL on MOUNTPT. MOUNTPT must be writable by you
and not sticky. DIAL is a dial string assuming one of the forms:
unix!SOCKET
tcp!HOST[!PORT]
virtio!CHANNEL
-
where SOCKET is the name of a file representing a socket, HOST is a hostname, PORT is a
port number or service name, and CHANNEL is a virtio channel name (currently ignored). -
indicates that 9p messages should be read/written on stdin/stdout. 9mount has several
options:
-i mount the file system with your uid/gid
-n dry-run, print mount command to stderr but don't actually mount anything
-s single attach mode - all users accessing the mount point see the same filesystem
(by default they'll each see a unique attach)
-u use the 9P2000.u extensions
-v use device mapping
-x exclusive access - other users cannot access the mount point
-a SPEC
SPEC determines which file tree to mount when attaching to file servers that export
multiple trees
-c CACHE
turns on caching using CACHE mode. Currently only loose cache mode is available,
which is suitable for exclusive read-only mounts.
-d DEBUG
comma separated list of channels for which to enable debug output. Possible
channels include: err, devel, 9p, vfs, conv, mux, trans, alloc, fcall.
-m MSIZE
specifies the maximum length of a single 9p message in bytes.
9bind performs a bind mount, making the tree visible at directory OLD also visible at
mount point NEW.
9umount unmounts a 9p filesystem previously mounted by you.
ENVIRONMENT
$USER the uname to provide to the server.
EXAMPLES
9mount -i 'unix!/tmp/ns.'$USER'.:0/factotum' $HOME/n/factotum
mount p9p's factotum interface
9mount 'tcp!sources.cs.bell-labs.com' $HOME/n/sources
import plan 9's "sources"
9mount -u -a/home/sqweek/mail 'tcp!wren!5640' $HOME/mail
import my maildir from my server(wren), being served by ufs
9mount -i 'tcp!wren' $HOME/n/wren; 9bind $HOME/n/wren/home/sqweek/mail $HOME/mail
again importing my maildir, this time serving via u9fs
