Ubuntu lsblk驱动器尺寸
Ubuntu lsblk驱动器尺寸
提问于 2019-06-23 03:10:50
我正在使用Ubuntu 18设置一个ZFS NAS，其中有8个硬盘驱动器用于存储。当我使用sudo lsblk -P检查驱动器名时，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。我做了sudo lsblk -Pa，然后我看到了sda，但是SIZE=""。我的问题是，SIZE=""是否意味着这个驱动器是坏的，需要替换，还是需要用这个驱动器做一些我不知道的事情？谢谢你的帮助。

输入sudo smartctl -iHAf brief -l error -l xerror /dev/sda后进行更新--这是输出：

是的，这很可能意味着驱动器是坏的。一些磁盘驱动器通过将其大小报告为零表示其内部诊断失败，另一些磁盘驱动器可能在相同情况下使用“未插入媒体”错误代码响应命令。
您可能应该检查磁盘的智能状态：smartctl -iHAf brief -l error -l xerror /dev/sda应该输出最重要的智能磁盘健康信息的简明报告。
此外，您可能需要查看dmesg -H的输出以获得错误消息。
