arm板子挂在nfs失败-mount: wrong fs type

1.提示错误如下：

# mount -t nfs -o nolock 192.168.12.90:/home/light/nfs /mnt/nfs

mount: wrong fs type, bad option, bad superblock on 192.168.12.90:/home/light/nfs,

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

2.查资料提示少mount.nfs文件，找来后，错误消失了，但是挂载后没反应。

3.pc系统中本机挂载没问题,还是板子问题

4.最后加上busybox指令后解决。

# busybox mount -t nfs -o nolock 192.168.12.90:/home/light/nfs /mnt/nfs

# umount /mnt/nfs
