Mounting an NFS Volume
The mounting of NFS volumes closely resembles regular file systems. Invoke mount using the following syntax:[81]
#mount -t nfsnfs_volume local_dir options
nfs_volume is given as
remote_host:remote_dir.
Since this notation is unique to NFS filesystems, you can leave out
the -t nfs option.
There are a number of additional options that you can specify to
mount upon mounting an NFS volume. These may be
given either following the -o switch on the
command line or in the options field of the
/etc/fstab entry for the volume. In both cases,
multiple options are separated by commas and must not
contain any whitespace characters. Options specified on the command
line always override those given in the fstab
file.
Here is a sample entry from /etc/fstab:
# volume mount point type options news:/var/spool/news /var/spool/news nfs timeo=14,intr
This volume can then be mounted using this command:
# mount news:/var/spool/news
In the absence of an fstab entry, NFS
mount invocations look a lot uglier. For instance,
suppose you mount your users’ home directories from a machine named
moonshot, which uses a default
block size of 4 K for read/write operations. You might increase the
block size to 8 K to obtain better performance by issuing the command:
# mount moonshot:/home /home -o rsize=8192,wsize=8192
The list of all valid options is described in its entirety in the
nfs(5) manual page. The following is a partial list
of options you would probably want to use:
- rsize=n ...
