Not able to mount nfs share on client "mount: wrong fs type, bad option, bad superblock"

Solution Verified - Updated -

Issue

  • Not able to mount nfs share on client "mount: wrong fs type, bad option, bad superblock"
# mount nfs-server:/export/test /tmp/test
mount: wrong fs type, bad option, bad superblock on nfs-server:/export/test,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

# mount -v -o nfsvers=3 nfs-server:/export/test /tmp/test
mount: /tmp/test: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program.
