mount_nfs(1M) mount_nfs(1M)
posix Request POSIX.1 semantics for the file system. Requires a mount NFS Ver-
sion 2 mountd on the server. See mountd (1M).
proto=netid netid is a value of network_id field from entry in the
/etc/netconfig
file.
By default, the transport protocol used for the NFS mount will be first avail-
able connection-oriented transport supported on both the client and the server.
If no connection-oriented transport is found, then the first available connec-
tionless transport is used. This default behavior can be overridden with the
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 (quota) or prevent (
noquota) the quota command 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. See
quota (1).
readdir Disable the READDIRPLUS functionality, which is used by default on an NFS
Version 3 mount point, and use the NFS Version 2
READDIR functionality
instead. The performance of applications that read huge directories over NFS
will vary between NFS Version 2 and NFS Version 3 depending on the type of
information that the applications need. The
find command will be faster
using NFS Version 3 READDIRPLUS while the ls command will be faster
using NFS Version 2 READDIR. The readdir option must be used on a case
by case basis depending upon the application. There is no effect on an NFS
Version 2 mount point.
remount Remount 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 (rw) or read-only (ro). The default is
rw.
rsize=n Set the read buffer size to n bytes. The default value is
32768 when using
Version 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. See nfssec (5) for the available
security mode options.
If
sec= is not specified, then the default action is to use AUTH_SYS over NFS
Version 2 mounts, or to negotiate a security 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.
secure This option is equivalent to the sec=dh option (Diffie-Hellman public key sys-
tem).
suid | nosuid Setuid execution is allowed (suid) or disallowed (nosuid). 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 sup-
port NFS Version 3 protocol, then the NFS mount will use NFS Version 2
