Generally, you will see server not responding message or computer just freezes. You can pass the following option while mounting remote shared/exported NFS server:
- 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 timeo=time. This 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.
- timeo N: This timeout value is expressed in tenths of a second
- retrans : The number of timeouts allowed before the client gives up and displays the Server not responding message. The mount fails soon after.
- proto tcp/udp: The protocol (Either TCP or UDP) used when attempting to mount the server.
# mount -t nfs -o soft,timeo=900,retrans=3,vers=3, proto=tcp remotenfsserver:/home/data /mnt/nfs-mnt-point
# mount.nfs4 -o soft,timeo=900,retrans=3,vers=3, proto=tcp nas01:/data /data
