一.问题描述某一台跑批服务器硬盘无法正常读写，提示input/output error，服务器每天均需使用，询问情况后发现服务器首先为硬盘故障，更换硬盘后提示此错误（RAID已正常同步）
二.排查问题

出现问题，先查看日志，收集日志进行分析查看，日志分析结果如下：

查看日志发现磁盘已经offline，并且文件系统已经异常.三.解决方案1.手动将此硬盘设置为online
# echo running > /sys/block/sdd/device/state2.查询是否为running
cat /sys/block/sdd/device/state3.修复文件系统，并确认硬盘处于umount状态（视情况而定，如无法umount则只能进行重启，我是进行的重启操作）4.开始修复
XFS : Corruption detected. Unmount and run xfs_repair
官方文档如下:https://access.redhat.com/sol...5.按照上述方法修复完成后，再进行mount操作
