241
242 retrans=n
243 Set the number of NFS retransmissions to n. The default value
244 is 5. For connection-oriented transports, this option has no
245 effect because it is assumed that the transport performs
246 retransmissions on behalf of NFS.
247
248
249 retry=n
250 The number of times to retry the mount operation. The default
251 for the mount command is 10000.
252
253 The default for the automounter is 0, in other words, do not
254 retry. You might find it useful to increase this value on
255 heavily loaded servers, where automounter traffic is dropped,
256 causing unnecessary server not responding errors.
257
258
259 rsize=n
260 Set the read buffer size to a maximum of n bytes. The default
261 value is 1048576 when using connection-orientated transports
262 with Version 3 or Version 4 of the NFS protocol, and 32768 when
263 using connection-less transports. The default can be negotiated
264 down if the server prefers a smaller transfer size. "Read"
265 operations may not necessarily use the maximum buffer size.
266 When using Version 2, the default value is 32768 for all
267 transports.
268
269
270 sec=mode
271 Set the security mode for NFS transactions. If sec= is not
272 specified, then the default action is to use AUTH_SYS over NFS
273 Version 2 mounts, use a user-configured default auth over NFS
274 version 3 mounts, or to negotiate a mode over Version 4
275 mounts.
276
277 The preferred mode for NFS Version 3 mounts is the default mode
278 specified in /etc/nfssec.conf (see nfssec.conf(4)) on the
279 client. If there is no default configured in this file or if
280 the server does not export using the client's default mode,
281 then the client picks the first mode that it supports in the
282 array of modes returned by the server. These alternatives are
299 Set the NFS timeout to n tenths of a second. The default value
300 is 11 tenths of a second for connectionless transports, and 600
301 tenths of a second for connection-oriented transports. This
302 value is ignored for connectionless transports. Such transports
303 might implement their own timeouts, which are outside the
304 control of NFS.
305
306
307 vers=NFS version number
308 By default, the version of NFS protocol used between the client
309 and the server is the highest one available on both systems.
310 The default maximum for the client is Version 4. This can be
311 changed by setting the NFS_CLIENT_VERSMAX parameter in
312 /etc/default/nfs to a valid version (2, 3, or 4). If the NFS
313 server does not support the client's default maximum, the next
314 lowest version attempted until a matching version is found.
315
316
317 wsize=n
318 Set the write buffer size to a maximum of n bytes. The default
319 value is 1048576 when using connection-orientated transports
320 with Version 3 or Version 4 of the NFS protocol, and 32768 when
321 using connection-less transports. The default can be negotiated
322 down if the server prefers a smaller transfer size. "Write"
323 operations may not necessarily use the maximum buffer size.
324 When using Version 2, the default value is 32768 for all
325 transports.
326
327
328 xattr | noxattr
329 Allow or disallow the creation and manipulation of extended
330 attributes. The default is xattr. See fsattr(5) for a
331 description of extended attributes.
332
333
334
335 -O
336 Overlay mount. Allow the file system to be mounted over an existing
337 mount point, making the underlying file system inaccessible. If a
338 mount is attempted on a pre-existing mount point without setting
339 this flag, the mount fails, producing the error "device busy."
340

620 mount_cachefs cannot be used with replicated NFS mounts or any NFS
621 Version 4 mount.

625 smf(5), under the service identifier:
