nfs挂载错误wrong fs type, bad option, bad superblock

今天碰到一个nfs挂载错误的问题，错误提示如下：

mount: wrong fs type, bad option, bad superblock on 125.64.41.244:/data/img,
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

根据错误提示，查看/sbin/mount.文件，果然发现没有/sbin/mount.nfs的文件，安装nfs-utils即可

解决方法：

代码如下	复制代码
apt-get install nfs-common 或者 yum install nfs-utils

安装之后，/sbin/下面多了两个mount文件，分别是mount.nfs和mount.nfs4：

代码如下	复制代码
[root@web data]# ll /sbin/mount* -rwsr-xr-x. 1 root root 123776 11月 22 2013 /sbin/mount.nfs lrwxrwxrwx. 1 root root 9 6月 9 13:41 /sbin/mount.nfs4 -> mount.nfs -rwxr-xr-x. 1 root root 1338 2月 22 2013 /sbin/mount.tmpfs
