掛載nfs提示 wrong fs type, bad option

[root@k8s-node02 ~]# mount -t nfs 192.168.56.120:/app/grafana/data /mnt
mount: wrong fs type, bad option, bad superblock on 192.168.56.120:/app/grafana/data,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)

   In some cases useful info is found in syslog - try
   dmesg | tail or so.
