我的服务器开始无缘无故地随机重启。
我一直在尝试找出问题所在，起初我以为是虚拟化/proxmox 或某种原因导致了重启。
但现在我开始怀疑我的硬盘存储出现故障。你们觉得呢，2 个月前的硬盘已经坏了吗？
root@proxmox ~ # smartctl -a /dev/sda

让我担心的是：
1 Raw_Read_Error_Rate 0x000f 082 064 044 Pre-fail Always - 159956709
真的是这样吗？我读得对吗？有 159956709 个错误？
答案1
即使在 GUI smartmontools（我认为使用 smartctl）中，这些条目也很难理解。您的开机时间为 28,583 小时，上次扩展测试为 23,986 小时，因此如果您担心，可以再次运行该测试。如果这些测试通过并且您的 SMART 错误日志为空，那么我认为您的驱动器没有问题，问题出在其他地方。如果您真的很偏执，您可以启动制造商/OEM 驱动器测试工具（链接至 SeaTools）使用他们的测试；但是我相信 smartctl，因为 OEM 有动机（叫我偏执狂）告诉你驱动器没问题，但事实并非如此（因为他们可能必须保证这一点）
