我们管理的（但没有物理访问权限）带有软件 RAID1 的 Debian 6 机器正在发出有关磁盘（ATA1 和 ATA2）的各种错误。
我不知道这是怎么回事。磁盘似乎没问题。我们没有注意到服务器所服务的网站出现挂起或其他问题。
我知道这是一个“可能是任何事情”的问题，但我真的希望有人能够帮助我。
眼镜：
- Debian 6，运行 Xen 虚拟机管理程序
- 磁盘：250 GB WDC WD2500AAKX-00U6AA0
- 支持并启用 NCQ：ata2.00：488397168 个扇区，多 16：LBA48 NCQ（深度 31/32），AA
- SATA 控制器：英特尔公司 Patsburg 6 端口 SATA AHCI 控制器（rev 06）
- 内核：2.6.32-5-xen-amd64
- 内存：16GB
- 英特尔 (R) 至强 (R) CPU E5-2620 0 @ 2.00GHz
以下是一些错误：

答案1
握手似乎表明控制器无法与驱动器通信。我怀疑是电气干扰、电缆损坏或控制器损坏。在后一种情况下，主板需要更换。您只能通过排除法（分别测试每个硬件）找到罪魁祸首。
