m
mount_nfs(1M) mount_nfs(1M)
proto=netid option.
public The public option forces the use of the public file handle when connecting to
the NFS server. The resource specified might not have an NFS URL. See the
discussion on URL’s and the public Option under NFS FILE SYSTEMS for a
more detailed discussion.
quota | noquota Enable or prevent quota(1) to check whether the user is over quota on this file
system; if the file system has quotas enabled on the server, quotas are still
checked for operations on this file system.
remount Remounts a read-only file system as read-write (using the
rw option).
retrans=n Set the number of NFS retransmissions to n. The default value is
5.For
connection-oriented transports, this option has no effect because it is assumed
that the transport performs retransmissions on behalf of NFS.
retry=n The number of times to retry the
mount operation. The default for the mount
command is 1.
rw | ro resource is mounted read-write or read-only. The default is rw.
rsize=n Set the read buffer size to n bytes. The default value is 32768
when using Ver-
sion 3 of the NFS protocol. The default can be negotiated down if the server
prefers a smaller transfer size. When using Version 2, the default value is
8192.
sec=mode Set the security mode for NFS transactions. If
sec= is not specified, then the
default action is to use
AUTH_SYS over NFS Version 2 mounts, or to negotiate a
mode over NFS Version 3 mounts. NFS Version 3 mounts negotiate a security
mode when the server returns an array of security modes. The client picks the
first mode in the array that is supported on the client. Only one mode can be
specified with the sec= option. See nfssec(5) for the available mode options.
secure This option is equivalent to sec=dh.
suid | nosuid Setuid execution allowed or disallowed. The default is suid.
timeo=n Set the NFS timeout to n tenths of a second. The default value is 11
tenths of a
second for connectionless transports, and
600 tenths of a second for connection-
oriented transports.
vers=NFS_version_number
By default, the version of NFS protocol used between the client and the server
is the highest one available on both systems. If the NFS server does not support
NFS Version 3 protocol, then the NFS mount will use NFS Version 2 protocol.
wsize=n Set the write buffer size to n bytes. The default value is
32768 when using Ver-
sion 3 of the NFS protocol. The default can be negotiated down if the server
prefers a smaller transfer size. When using Version 2, the default value is
8192.
-q When processing an unknown specific_option, the mount utility prints a warning message and
processes the next one. This option prevents printing the warning message.
-O Overlay mount. Allow the file system to be mounted over an existing mount point, making the under-
lying file system inaccessible. If a mount is attempted on a pre-existing mount point without setting
this flag, the mount will fail, producing the error device busy.
Options (umount)
-a Attempt to unmount all NFS file systems described in /etc/mnttab .
-d Print debug messages to stderr. This option is to be used by HP support engineers.
-f Forcibly unmount a file system. Without this option, the umount utility does not allow a file system
to be unmounted if a file on the file system is busy. Using this option can cause data loss for open
files; programs which access files after the file system has been unmounted will get an error (EIO).
