Overview
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. Supported modes are loose (suitable for exclusive read-only mounts), fscache, and mmap.
-
-d DEBUG -
comma seperated 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. Must be less than or equal to 8192 for non-root users.
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
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 |
