acdmax (INTEGER)

Sets the maximum number of seconds that NFS waits before checking to see if a folder attribute, such as modification time, has changed. A smaller value assures earlier detection that a folder has been modified. A larger value improves performance by decreasing the frequency of NFS operations. 

acdmin (INTEGER)

Sets the minimum number of seconds that NFS waits before checking to see if a folder attribute, such as modification time, has changed. A smaller value assures earlier detection that a folder has been modified. A larger value improves performance by decreasing the frequency of NFS operations. 

acoff (BOOLEAN)

Disables attribute caching. Caching can improve NFS file access time. 

arch (BOOLEAN)

To conform to DOS conventions, you can set the archive bit to true. 

acrmax (INTEGER)

Sets the maximum number of seconds that NFS waits before checking to see if a file attribute, such as file size, has changed. A smaller value assures earlier detection that a file has been modified. A larger value improves performance by decreasing the frequency of NFS operations. 

acrmin (INTEGER)

Sets the minimum number of seconds that NFS waits before checking to see if a file attribute, such as file size, has changed. A smaller value assures earlier detection that a folder has been modified. A larger value improves performance by decreasing the frequency of NFS operations. 

bsd (BOOLEAN)

Uses BSD directory folder creation syntax. 

case=[yes, no]

Handles remote drive with case sensitivity in file names. Default is no case sensitivity. case=yes automatically sets cs (case sensitive). case=no automatically clears cs.

cf (BOOLEAN)

Uses only the preferred case (either upper or lower) for file name operations. If not specified, you can create files and folders in either uppercase or lowercase. 

Specifying cu and cf forces uppercase. If both options are specified, when created, the folder myfolder is automatically changed to MYFOLDER.

cs (BOOLEAN)

Looks up file names while preserving the case in which you entered the file name search key. When this option is used, file operations are case sensitive, which is faster than case-insensitive operations. 

cu (BOOLEAN)

Instructs NFS Client to use uppercase letters as the preferred case for looking up and creating file names. 

lock (BOOLEAN)

Specifies whether to use the built-in NFS capability to prevent others from changing files you are modifying. The default is no.

map=mapchar

Specifies a file name mapping character. 

Example:

map=^

nfsver (INTEGER)

Specifies which version of NFS to use (0, 2, or 3). If the servers to which you most often connect support only one version, configure that version as a default. The default value 0 automatically tries v3 first and then v2.

Example:

nfsver=2 specifies NFS v2

port (INTEGER)

Default is 2049. The NFS specification suggests port number 2049 as the standard NFS server port. Your NFS servers may be configured to use another port number. 

preserve

This option is ignored 

retries (INTEGER)

Specifies the number of times an NFS client attempts to reach an NFS server. The default value is 5. 

ro | rw

Mounts the directory in read-only or in read-write mode. Default is rw. The ro option connects drives so that you can read, but cannot write, their files.

rsize (INTEGER)

Specifies the size (in bytes) of a data block read from a file during an NFS data transfer. A larger size increases NFS performance if the underlying network hardware can handle the larger size. The default read and write size is 32,768 bytes for TCP, and 8 kilobytes for UDP. 

Example:

This example sets the read size to 1024 bytes.  

rsize=1024

share=[yes, no]

Specifies whether to use the built-in NFS capability to prevent others from changing files that you are modifying. The default is no.

share=yes automatically sets lock.

share=no automatically clears lock.

trans [TCP|UDP]

Specifies transport. Using the UDP transport speeds up network traffic by reducing packet overhead. TCP works better when high reliability of packet transmissions is a requirement. If not set, the NFS client tries TCP first and then UDP.  

Example:

trans=TCP sets the transport to TCP.

type

This option is ignored 

umask

Sets the file creation mask.  

Example:

umask=022

wsize

Specifies the size (in bytes) of a data block written to a file during an NFS data transfer. A larger size increases NFS performance if the underlying network hardware can handle the larger size. The default read and write size is 32,768 bytes for TCP, and 8 kilobytes for UDP. 

Example:

wsize=8192, sets the write size to 8192 bytes.
