Unable to mount nfs filesystem using nfsv4

Solution Verified - Updated -

Issue

  • NFS client is mounting the filesystem shares with only version 3 and it's unable to mount it as version 4.

  • NFS share 192.168.0.2:/nfsshare2/test2 can be mounted with NFS version 3 but while mounting with version 4.1,
    It is saying "No such file or directory"

    # sudo mount -o proto=tcp,vers=4.0 192.168.0.2:/nfsshare2/test2 /test2
mount.nfs: mounting 192.168.0.2:/nfsshare2/test2 failed, reason given by server: No such file or directory
