In both man pages. The generic options (ro, rw, nosuid etc.) are
explained in mount(8), while the NFS mount options are explained in
mount_nfs(8):
The options are:
-3 Use the NFS Version 3 protocol (Version 2 is the default).
-D Used with NQNFS to set the ``dead server threshold'' to the spec-
-I Set the readdir read size to the specified value. The value
-K Pass Kerberos authenticators to the server for client-to-server
-L Used with NQNFS to set the lease term to the specified number of
-P Use a reserved socket port number. This is useful for mounting
-R Set the retry count for doing the mount to the specified value.
-T Use TCP transport instead of UDP. This is recommended for
-U Force the mount protocol to use UDP transport, even for TCP NFS
-a Set the read-ahead count to the specified value. This may be in
-b If an initial attempt to contact the server fails, fork off a
-c For UDP mount points, do not do a connect(2). This must be used
-d Turn off the dynamic retransmit timeout estimator. This may be
-g Set the maximum size of the group list for the credentials to the
-i Make the mount interruptible, which implies that file system
-l Used with NQNFS and NFSV3 to specify that the ReaddirPlus RPC
-m Set the Kerberos realm to the string argument. Used with the -K
-q Use the leasing extensions to the NFS Version 3 protocol to main-
-r Set the read data size to the specified value. It should normal-
-s A soft mount, which implies that file system calls will fail af-
-t Set the initial retransmit timeout to the specified value. May
-w Set the write data size to the specified value. Ditto the com-
-x Set the retransmit timeout count for soft mounts to the specified
That is, you can:
mount -t nfs -o -r=1024,-w=1024,-i,-b machine:/resource /mountpoint
^^^^^^^^^^^^^^^^^^^^^
These are the options as mentioned above.
You can also say
mount -t nfs -o intr,bg machine:/resource /mountpoint
Both of these options are not explained, we've still got an open PR
for it (735, responsible: wollman ;), but these options are considered
legacy that will not be explained. (At least, that's the net result
from the discussion as you can read in GNATS.)
