Just setting up a backup drive for a VPS and needed to remember about the default missing NFS software which means that you get an error running a mount on system:
root@server:~# echo "7126679-hostbackup.com:/backups/22.214.171.124 /backups nfs rw,hard,intr,noexec,rsize=8192,wsize=8192,nfsvers=4,noatime,_netdev,nolock 0 0" >> /etc/fstab; mount -a
mount: wrong fs type, bad option, bad superblock on 7126679-hostbackup.com:/backups/126.96.36.199, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.
helper program) In some cases useful info is found in syslog - try dmesg | tail or so
With a simple install of the
nfs-common package we can get this up and running without issue:
apt-get install nfs-common
mount -a then correctly mounts the network volume, in this case used for backups.
