我想知道为什么我的服务器崩溃了。启动几分钟后它会自动重启
stress-ng -d 9
我收到的最新日志如下：

（服务器在最后一行中间崩溃了！）
我检查了 smartctl 并且一切正常：

磁盘的速度似乎也还可以：
root@aaa:/home/customer# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 24102 MB in 2.00 seconds = 12063.26 MB/sec
Timing buffered disk reads: 968 MB in 3.00 seconds = 322.25 MB/sec
root@aaa:/home/customer# hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 24290 MB in 2.00 seconds = 12156.88 MB/sec
Timing buffered disk reads: 968 MB in 3.00 seconds = 322.28 MB/sec
任何想法？
答案1
可能值得从测试中剔除该特定 HDD，例如通过在外部安装的 HDD 上重新运行测试，以查看它是一般的内核问题还是该特定驱动器的问题。-d HDD Stress-ng Stressor 只会用大量通用的读/写模式敲击文件系统，因此令人惊讶的是它会导致这种挂起。因此，我假设这可能是该特定驱动器的问题。
