Ubuntu lsblk 驱动器大小

我正在使用 Ubuntu 18 设置 ZFS NAS，并使用 8 个硬盘进行存储。当我用来sudo lsblk -P检查驱动器名称时，我只看到sdb-sdh.我知道这是因为它会跳过大小为 0 的驱动器。我这样做了sudo lsblk -Pa，然后我看到了sda，但是SIZE=""。我的问题是，这是否SIZE=""意味着该驱动器已损坏并且需要更换，或者是否需要对该驱动器执行其他我不知道的操作？感谢您的帮助。

是的，这很可能意味着驱动器坏了。某些磁盘驱动器通过将其大小报告为零来表明它们的内部诊断失败，而其他磁盘驱动器可能会在相同情况下以“未插入介质”错误代码响应命令。

您可能应该检查磁盘的 SMART 状态：smartctl -iHAf brief -l error -l xerror /dev/sda应该输出最重要的 SMART 磁盘运行状况信息的简明报告。

另外，您可能想查看dmesg -H错误消息的输出。
