在我拥有的带有 HDD 或 SSD 的服务器上，我有一个定期运行的 cron：

/usr/sbin/smartctl --test=short/long /dev/sd1

（对于每个磁盘）

当它运行时，它只是查看 的输出/usr/sbin/smartctl -c /dev/sd1，循环直到它不再包含：

[0-9]+% of test remaining.

然后检查它是否在没有错误的情况下完成：

(   0)  The previous self-test routine completed

但是，从 7.0 版开始，它似乎smartctl还不支持对 NVMe 的测试，并且按照：https ://www.smartmontools.org/wiki/NVMe_Support

它确实说

smartd 守护进程跟踪运行状况 (-H)、错误计数 (-l error) 和温度 (-W DIFF,INFO,CRIT)

但实际运行测试的是什么？除非我们运行短/长测试，否则我不确定是否输出-H和更新？-l

我也读过关于nvme-cli，但我似乎没有找到用它在磁盘上运行健康测试的方法。

有任何想法吗？

在这里使用 CentOS 7。

我有一个降级的 RAID-1 设置，我正在尝试解决问题，无论它是完全死机（并且需要将驱动器送回供应商）还是可以恢复。

所以我跑了smartctl：

root@linux:~# smartctl -l selftest /dev/sda

看起来不错。让我们看看其他的东西：

我试图查看输出，但不幸的是我不是分析 smartctl 输出的专家。它说驱动器通过了测试：

SMART overall-health self-assessment test result: PASSED

在门槛部分，一切看起来都不错（这是一个相当新的 WD Red HDD，几个月前）。

在输出结束时，虽然有很多错误。我试图查找它们，但没有运气。

另一方面，我根本无法使用磁盘：

root@idealib:~# fdisk /dev/sda

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

fdisk: cannot open /dev/sda: Input/output error

dmesg看起来也很糟糕：

在我可以 100% 确定磁盘有故障并且需要更换之前，我还应该进行哪些其他测试？或者它已经死了，我应该接受它？:)

如果下面的驱动器出现故障，我需要您的意见。

当我运行“smartctl -a /dev/sda -d megaraid,1”时，输出末尾会出现 2 个错误，说明“错误：LBA 上的 WP”。我在 SMART 参数中没有看到任何可疑之处。

这是“smartctl -a /dev/sda -d megaraid,1”的完整输出。

此 HDD 是 RAID 1（镜像）硬件配置中的两个 HDD 之一，位于 Dell PowerEdge 服务器上的 Dell H330 控制器上。

稍后编辑1：

我还检查了 PowerEdge 服务器上的 iDRAC，并且在存储菜单 > 摘要 > 最近记录的存储事件中，我发现了与发生 2 个 SMART 错误相对应的事件。

事件状态：“在恢复期间更正了插槽 1 中 RAID 控制器背板 1 中磁盘 1 上的磁盘介质错误”。请在屏幕截图下方找到。

来自 iDRAC > 存储菜单 > 摘要 > 最近记录的存储事件的图像

稍后编辑2：

几天后，Current_Pending_Sector 在几个小时内增加到 1，然后又减少到 0。

Reallocated_Sector_Ct、Reallocated_Event_Count 和 Offline_Uncorrectable 始终保持为 0。

SMART 错误日志中还出现了另一个错误：“错误：LBA 的 UNC”。

虽然，iDRAC 中没有出现其他错误。

我们决定用新驱动器更换驱动器，因为我们不再信任该驱动器。

谢谢！

我有一个外部 Freecom 硬盘（内置三星驱动器），通过 USB 连接并使用它自己的电源。

磁盘会在随机的时间间隔（从几个小时到一个月）断开自身连接。我倾向于责怪操作系统，因为同一个驱动器在连接到 TP-Link 路由器的 USB 端口时没有问题。

无论如何，只是为了确保我使用 smartctl 执行了扩展的 SMART 自检并完成了Completed: read failure 30%消息。因此，我使用 e2fsck 进行了额外的测试。我花了整整一晚上的时间来测试这个 1.5TB 的硬盘。测试完成，没有任何错误。

我很困惑——我应该相信 SMART 自检还是 e2feck 结果？此外，SMART 健康状态为“通过”，简短的自检也很好。检查通常的嫌疑人 - USB 电缆已更换为新电缆，并检查外部电源。想法？我应该购买新驱动器还是安全？SMART 或 e2fsck 是更可靠的健康状况来源吗？

我目前正在设置智能监控，我对命令有疑问

smartctl -H /dev/sda

=== START OF READ SMART DATA SECTION ===
SMART Health Status: OK

这实际上是对磁盘运行任何东西，还是只是轮询 SmartMonTools 当前可用的日志/数据。

我了解并正在考虑通过短期和长期测试运行 smartd，但这将由 smartd 管理。我的脚本很简单，它只是 greps 健康状态 OK 并根据查找结果失败/通过。它还显示“smartctl -all /dev/sda”，我也想知道这一点。

我只是想确定一下，因为

我认为两者smartctl -H /dev/sda && smartctl -all /dev/sda在运行时实际上都没有进行任何测试，它们只是轮询可用数据。有人可以确认吗？

原因是我经常用我的网络监控软件（目前每 15m）轮询这个数据，但如果它不影响磁盘，我会留下它并使用 smartd 安排实际的自测，它会 100% 读取/写/测试磁盘。

我有一个使用由 2 个 SAS 驱动器组成的 Promise FastTrack TX2650 的 RAID1。他们的 Linux 设备名称是什么？就像sda是第一个 sata 驱动器。我有 Windows 服务器，所以我无法直接查看它，但需要此信息以供smartctl使用。

更新。我找到了如何访问 RAID：（smartctl -d scsi sdb因为我也有一个 SATA 驱动器）。但在这种情况下，尽管我想获取有关驱动器本身的信息，但我只获得了有关 raid 控制器的信息。可能吗？Promises 的控制面板仅提供有关其健康状态（布尔值）的信息，我想要更多。大多数情况下，我需要有关温度的信息。

我的 Linux 系统开始在 syslog 中抛出 SMART 错误。我对其进行了追踪，并认为问题出在磁盘上的单个块上。如何轻松地让磁盘重新分配那个块？我想知道在这个过程中什么文件被破坏了。（我知道，如果磁盘上的一个块发生故障，其他块可能会跟随；我有一个很好的持续备份，只是想尝试保持该磁盘正常工作。）

在网络上搜索会导致Bad block HOWTO，它描述了在卸载磁盘上的手动过程。这似乎很复杂且容易出错。是否有工具可以在 Linux 中自动执行此过程？我唯一的其他选择是制造商的诊断工具，但我认为这会破坏坏块，而不会报告损坏的内容。最坏的情况，它可能是文件系统元数据。

有问题的磁盘是主系统分区。使用 ext3fs 和 LVM。这是来自 syslog 的错误日志和来自 smartctl 的相关位。
