192.168.10.151:/export/common/general /u01/common/general nfs rw,bg,hard,nointr,rsize=131072,wsize=131072,tcp,vers=3The hard mount option can cause a stuck mount and leave processes in an uninterpretable sleep state without any way to kill it other than rebooting the server. Depending on your NFS purpose and whether the system is mission critical, you might want to consider the use of soft mount using the TCP protocol and an increased retrans option. A soft mount option will at least return an error and any sophisticated program should handle the situation similar to an I/O error.
NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directoryCan you try a simple manual mount to see if that works and what error it returns?
