交换设备上的写入错误，结果: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK

Question

我在1&1的根服务器在HTTP和SSH上没有响应，所以我登录到串行控制台。它淹没了我的连接无休止的错误信息，如下面引用。

我启动了一个重新启动，现在一切似乎都正常了。

谷歌后，我安装了智能was，并进行了一个简短的自我测试，这告诉我，设备是健康的。

这很可能很快就会发生磁盘故障，还是仅仅是某个程序失控呢？我想，当大量内存被错误程序占用时，交换设备也会变得满？我怎么才能确定？

一周前，当我在没有经过适当调查的情况下重新启动时，服务器已经没有反应了。

服务器正在CentOS上运行。

Answer 1

我很害怕这个。这是一个已知的问题与特定的驱动模式。使用其他驱动器。
