Ubuntu NFS – Troubleshooting ‘Mount: Wrong FS Type, Bad Option, Bad Superblock’

nfsUbuntu

This is what I got on server:

manuel@server ~ $ cat /etc/exports
  /var/share    192.168.178.20(rw, sync)
manuel@server ~ $ cat /etc/hosts.allow 
  portmap: 192.168.178.20
manuel@server /etc $ cat /proc/filesystems | grep nfs
  nodev nfs
  nodev nfs4

This is what I get on my machine:

manuel@Timeline:~$ sudo mount -t nfs 192.168.178.2:/var/share /media/share/
   mount: wrong fs type, bad option, bad superblock on 192.168.178.2:/exports/var/share,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       Manchmal liefert das Syslog wertvolle Informationen – versuchen
       Sie  dmesg | tail  oder so

server is Raspbian (Debian Wheezy)
Timeline is Ubuntu 12.04

Run exportfs -a on the server machine.

Also both machines have all of the needed NFS support packages and have nfs support? You can find if the kernel supports a specific filesystem by examining the output of cat /proc/filesystems.

And yes, the filename of the export file needs to be /etc/exports

Finally, check to see if you have enabled the NFS daemons during startup.
