![]() – Specify nointr if users might damage critical data by manually interrupting an NFS request, and you would rather have the system hang while the server is down than risk losing data between the client and the server. If a hard mount is interruptible, a user may press -C or issue the kill command to interrupt an NFS mount that is hanging indefinitely because a server is down. – Specify intr if users are not likely to damage critical data by manually interrupting an NFS request. ![]() Any processes using the mounted directory will return errors if the server goes down. When NFS tries to access a soft-mounted directory, it gives up and returns an error message after trying retrans times (see the retrans option, later). – Specify soft if the server is unreliable and you want to prevent systems from hanging when the server is down. Interruptible hard mounts may be interrupted with CTRL-C or kill (see the intr option, later). If the server goes down, any processes using the mounted directory hang until the server comes back up and then continue processing without errors. When NFS tries to access a hard-mounted directory, it keeps trying until it succeeds or someone interrupts its attempts. – Specify hard if users will be writing to the mounted directory or running programs located in it.
