Redhat AS3操作特别慢是怎么回事啊？

[weixin_38053353]

这台服务器是用作邮件服务器，上架半年多来一直工作良好，但是昨天晚上死掉了。　
今天早上过来把它重启连上去，发现ssh连接要五分钟才能登录上去，在上面打个字符都要半天才能显示，web收发邮件是非常慢的，用客户端工具Foxmail或者outlook是根本连不上的。
我在查看dmesg的时候发现如下的错误：

[root@app root]# dmesg
{ DriveReady SeekComplete Error }

以下都是这样的报错……
请教一下，是不是硬盘损坏了？　我让托管商机房的人接显示器上服务器看，他说不能登录，也提示这样的错误。请大家给点解决意见，谢谢！在线等。
