+Instead of a textual option string, parsed by the kernel, the
|
||
|
|
+.I nfs4
|
||
|
|
+file system expects a binary argument of type
|
||
|
|
+.IR "struct nfs4_mount_data" .
|
||
|
|
+The program
|
||
|
|
+.B mount
|
||
|
|
+itself parses the following options of the form `tag=value',
|
||
|
|
+and puts them in the structure mentioned:

|
|
+.BI rsize= n,
|

|

|

+.BI proto= n,

|
||

|
+The option
|

|

|
|
+is accepted but ignored.
|
||
|
|
+Also the following Boolean options, possibly preceded by

|
||
|
|
+are recognized:
|
||
|
|
+.BR bg ,

|
+For details, see
|
||
|
|
+.BR nfs (5).
|
||
|

+
|
||
|
|
+Especially useful options include
|
||
|
|
+.TP
|
||
|
|
+.B rsize=32768,wsize=32768
|
||
|
|
+This will make your NFS connection faster than with the default
|
||
|
|
+buffer size of 4096.
|
||
|
|
+.TP
|
||
|
|
+.B hard
|
||
|
|
+The program accessing a file on a NFS mounted file system will hang
|
||
|
|
+when the server crashes. The process cannot be interrupted or
|
||
|
|
+killed unless you also specify
|
||
|
|
+.BR intr .
|
||
|
|
+When the NFS server is back online the program will continue undisturbed
|
||
|
|
+from where it was. This is probably what you want.
|
||
|
|
+.TP
|
||
|
|
+.B soft
|
||
|
|
+This option allows the kernel to time out if the NFS server is not
|
||
|
|
+responding for some time. The time can be
|
||
|
|
+specified with
|
||
|
|
+.BR timeo=time .
|
||
|
|
+This timeout value is expressed in tenths of a second.
|
||
|
|
+The
|
||
|
|
+.BR soft
|
||
|
|
+option might be useful if your NFS server sometimes doesn't respond
|
||
|
|
+or will be rebooted while some process tries to get a file from the server.
|
||
|
|
+Avoid using this option with
|
||
|
|
+.BR proto=udp
|
||
|
|
+or with a short timeout.
