我遇到這個問題。解決方法是：
1、我用最小化安裝了centos6.3，
然後mount 192.168.1.1:/nfs/data /data
出錯：
mount: wrong fs type, bad option, bad superblock on 192.168.181.189:/vpool1/ndata/ftpdata,
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
解決方法：
2、  yum install showmount -y
