我有一个网络服务器。大约100到150个虚拟主机。只是一些小网站。我的第一篇文章是:SATA hdd错误,但是现在我在其他磁盘上有了新的错误。1.如链接中所述,我对sata磁盘有问题。2.我放了其他磁盘.没有运气,mkfs.ext3 --在新磁盘上,mkfs运行时也会发出大量错误。3.下一步是更换sata电缆,这起到了帮助。之后,我可以格式化磁盘,并从备份开始文件传输。所以现在距离电缆和磁盘的更换已经4天了。现在,我在dmesg中看到了以下信息:

问题2: Raw_Read_Error_Rate每天增加20-30 %.可以吗?在磁盘上,sda值为7000,没有错误。

你的硬件失效了,修复它。

我没有彻底地阅读(并思考)你的问题,所以我可能错了,但是你可能想重新考虑驱动器的IOPS限制。我在某个地方读到(忘了链接),目前的消费者SATA驱动器平均只有75-100 IOPS,而企业SATA驱动器可以是这个数字的两倍(然后SAS驱动器可以再次翻倍)。IIRC这是一篇关于SSD的文章,在那里有可能有超过9000的IOPS!
