mount: wrong fs type, bad option, bad superblock on

在linux系统挂载FreeNAS的NFS服务，出现以下错误：
cloud@ubuntu01:/$ sudo mount -t nfs 192.168.1.169:/mnt/poos/vms /mnt/vms/
mount: wrong fs type, bad option, bad superblock on 192.168.1.169:/mnt/poos/vms,
       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


解决方案：
在终端下输入安装nfs-common即可解决，安装命令为sudo apt-get install nfs-common解决。
