1.异常信息

挂载远程nfs目录，有的可以正常挂载，有的机器出现下面错误

mount 192.168.122.10:ifs/data/backup /root/backup
mount: wrong fs type, bad option, bad superblock on 192.168.122.10.10:ifs/data/backup,
       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.解决方法

安装nfs客户端解决

centos:

yum -y install nfs-utils

ubuntu:

apt-get install nfs-common
