Error: mount: wrong fs type, bad option, bad superblock (NFS)

From ben.goodacre.name/tech

When mounting a NFS share on Ubuntu (and probably Debian) for the first time the following error can appear:

benyg@host:/mnt$ sudo mount -t nfs 10.x.x.x:/vol/vol1/rrd /mnt
mount: wrong fs type, bad option, bad superblock on 10.x.x.x:/vol/vol1/rrd,
       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

NFS Utilities

This usually occurs occurs because the nfs-common package needs to be installed:

• Debian / Ubuntu sudo apt-get install nfs-common
• Redhat/CentOS/Fedora sudo yum install nfs-common
• Mandriva urpmi nfs-common
• Gentoo emerge nfs-common

• Depending on distro nfs-utils and nfs-utils-lib may also need to be installed.

Portmap

Ensure portmap is running:

[benyg@host:~] $ rpcinfo -p
   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper
    100000    4     0    111  portmapper
    100000    3     0    111  portmapper
    100000    2     0    111  portmapper
    100024    1   udp  57055  status
    100024    1   tcp  51056  status

Output if it is not running:

[benyg@host:~] $ rpcinfo -p
rpcinfo: can't contact portmapper: RPC: Remote system error - No such file or directory

• Install it through the rpcbind package and start it.
