#mount -t nfs 10.12.1.23:/volume1/test /mnt/test
mount: wrong fs type, bad option, bad superblock on 10.12.1.230:/volume1/test,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.
In some cases useful info is found in syslog - try
dmesg | tail or so.
To solve this problem, you need to install nfs-utils package:
#yum install nfs-utils
In debian-based distros, you can try install nfs-common package:
#apt install nfs-common
That's all there is to it!
Have fun :)
