9mount, 9bind, 9umount - mount/unmount 9p filesystems
[ insuvx ] [ -a SPEC ] [ -c CACHE ] [ -d DEBUG ] [ -m MSIZE ] DIAL
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
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
has several options:
- mount the file system with your uid/gid
- dry-run, print mount command to stderr but don't actually
- single attach mode - all users accessing the mount point
see the same filesystem (by default they'll each see a unique attach)
- use the 9P2000.u extensions
- use device mapping
- exclusive access - other users cannot access the mount
- -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
- -d DEBUG
- comma separated list of channels for which to enable debug
output. Possible channels include: err, devel, 9p, vfs, conv, mux, trans,
- -m MSIZE
- specifies the maximum length of a single 9p message in
performs a bind mount, making the tree visible at directory OLD
also visible at mount point NEW.
unmounts a 9p filesystem previously mounted by you.
- the uname to provide to the server.
- 9mount -i 'unix!/tmp/ns.'$USER'.:0/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'
- import my maildir from my server(wren), being served by
- 9mount -i 'tcp!wren' $HOME/n/wren; 9bind
- again importing my maildir, this time serving via u9fs
truncates user names and SPECs to 249 characters. 9umount
doesn't know this, so you won't be able to unmount anything outside your home
directory. But you probably never bother logging out if your user name is that
doesn't update /etc/mtab.
only does a "shallow", non-recursive bind - any mounted
filesystems under the OLD tree will not appear mounted in the NEW tree.
If you 9bind
a non-9p filesystem outside your home directory,
won't let you unmount it.
