以下情况：

内核消息表明（至少对我而言）所有 4 个驱动器都存在问题，这让我相信可能是 sata 控制器有问题。

我所做的已经想通了（或相信已经想通了）

命令SECURITY FREEZE LOCK和DEVICE CONFIGURATION OVERLAY问题并不重要。

在阅读大约 20 个错误报告和大量文档时，一些链接确实建议禁用 NCQ，我这样做了。

首先是一台设备，在等待 1 天检查错误是否再次发生后，我为所有 4 台设备禁用了它

echo "1" >/sys/block/sdc/device/queue_depth

情况没有明显变化。

https://ata.wiki.kernel.org/index.php/Libata_error_messages

https://wiki.archlinux.org/index.php/Solid_State_Drives#Resolving_NCQ_errors

其他人建议使用 sata 电缆，甚至是板 + 驱动器之间的不兼容。

但是，由于我似乎要么在一个驱动器上遇到问题并且这填充到所有 4 个设备上，要么直接在所有 4 个设备上遇到问题，我无法进一步查明问题。

由于这是一个生产服务器，因此可以将此服务器关闭以进行维护（又名 bios/内核参数更改），但我希望尽可能防止这种情况发生。

根据主持人的说法，这可能与电源管理有关：

https://bugzilla.kernel.org/show_bug.cgi?id=74961 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1318218

echo "medium_power" >/sys/class/scsi_host/host0/link_power_management_policy 

在更改之前，此设置为max_performance.

这也没有帮助。

HDD/SDD 的 Smart Values 还可以，没有什么太明显的。

请注意，UDMA 值现在似乎仅为 33。

在服务器启动时，这是 sata 链接速度值：

[    3.161850] ata6: SATA link down (SStatus 0 SControl 300)
[    3.161867] ata2: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[    3.161882] ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[    3.161894] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[    3.161907] ata5: SATA link down (SStatus 0 SControl 300)

这种情况可能只发生在 HDD 的高负载上，我还没有测试它，因为它会明显影响服务器性能。

SSD 上没有负载，它们已安装但未被任何进程使用。

据我所知，RAM 是 ECC。

请让我知道我是否可以提供更多信息，因为我缺乏下一步该做什么的想法。
