This sets the time (in tenths of a second) the NFS client will wait for a request to complete. The default value is 7 (0.7 seconds). What happens after a timeout depends on whether you use the hard or soft option.

Explicitly mark this volume as hard-mounted. This is on by default. This option causes the server to report a message to the console when a major timeout occurs and continues trying indefinitely.

Soft-mount (as opposed to hard-mount) the driver. This option causes an I / O? error to be reported to the process attempting a file operation when a major timeout occurs.

Allow signals to interrupt an NFS call. Useful for aborting when the server doesn't respond.
