hard mount : it is the default value , the NFS client constantly attempts to connect to the NFS server (no message is displayed in the background) until the NFS server is mounted.
Soft mount : The client attempts to connect to the NFS server. When receiving an error message, the client stops the mount attempt and print related error information.
We recommend to use hard mount , if you just want to use soft mount , just replace the “hard” to “soft”
eg . mount -t nfs-o vers=3,proto=tcp,rsize=1048576,wsize=1048576,soft,intr,timeo=600192.168.50.16:/nfstest /mnt
