![随机内核恐慌,没有明显的罪魁祸首](https://linux22.com/image/152666/%E9%9A%8F%E6%9C%BA%E5%86%85%E6%A0%B8%E6%81%90%E6%85%8C%EF%BC%8C%E6%B2%A1%E6%9C%89%E6%98%8E%E6%98%BE%E7%9A%84%E7%BD%AA%E9%AD%81%E7%A5%B8%E9%A6%96.png)
前段时间,我把旧台式机改造成debian服务器,完美运行了半年。
但后来我决定将机器移到互联网连接更好的地方,并添加一堆硬盘,使其成为一个合适的存储服务器(可以说是自制的 NAS)。
从现在开始,服务器随机崩溃。有时,需要一个多月才能崩溃。有时,需要一天的时间。最近,崩溃频率约为2-3天。
查看 dmesg,每次崩溃的原因似乎都不同。我完全不知道崩溃的原因是什么。
设置
- CPU:Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz

- 该机器在 Linux 4.9.0-8-amd64 上运行 Debian Stretch
- Kdump 已安装
- 系统安装在三星SSD 840 PRO (128 GB)上
- 5 个 8 TB Western Digital Red HDD 用于存储
- HDD 最初使用 mdadm 进行软件 RAID5 配置,但现在由 ZFS 使用 raidz2 进行管理。
- Apache2(带有 nextcloud)和传输守护进程运行

更新
我在重新安装 RAM 模块之前和之后都运行了 memtest86(来自 memtest86.com 的原始版本): 内存测试日志
没有发现错误。
更新
重新安装 RAM 模块没有效果。所以我探索了新的假设。
我检查了是否有任何电气干扰,但碰撞时间与重型电机的使用之间没有相关性。
我还检查了磁盘访问和崩溃之间的相关性。看来,即使磁盘活动较少,崩溃也可能发生,但在某些磁盘活动下,崩溃发生的速度要快得多。例如,如果我并行读取所有磁盘 ( cat /dev/sdX > /dev/null
),我可能会在一小时内使机器崩溃。然而,SMART数据显示没有任何问题。这里的输出smartctl -a /dev/sdb
(其他磁盘看起来相同):

所以崩溃在某种程度上与磁盘有关,但我不知道如何。
答案1
查看日志,内核被污染,或在不受支持的状态下运行:
Tainted: P IO
污点标志列表可在内核文档。 P和O部分表示非GPL兼容许可的、外部构建的内核模块;最值得注意的是,其中列出了 ZFS 和相关模块。您提供的日志片段之一表明 ZFS 模块中发生了一般保护故障,但其余的都在内核的其他地方。此外,GPF 和双重故障是由处理器本身产生的,这意味着模块可能没有故障。
我更关心的是 I taint 标志。 I 标志的意思是“应用平台固件中的错误的解决方法”。这表明系统的 UEFI/BIOS 固件存在潜在的严重问题,可能会导致错误。在此开始之前您是否执行过 BIOS 更新,并且在进行硬件升级之前是否设置了此标志?
不幸的是,完整日志的链接不再有效,因此我无法提供更具体的帮助。完整的日志可能会提供有关系统正在解决的固件错误的详细信息,以及其他可能的故障指标。
