[root@cn-svn-multi-01 ~]# mount -t nfs 192.168.0.234:/mnt/nfs/test/nfs-1 /mnt
mount: wrong fs type, bad option, bad superblock on 192.168.0.234:/mnt/nfs/test/nfs-1,
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
