修复有热备用的ZFS退化池

Question

我有一个8镜像驱动器和一个热备用的池。镜像集中的一个驱动器失败了，但我无法判断是否自动添加了热备用。备品的状态是“正在使用”，扫描显示它重新镀银了1.7T。镜像-0仍然显示降级。镜像还是我需要发布一个"zpool替换c0t12d1 c0t21d1“？

zpool status
pool: primary_vol
state: DEGRADED

        attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or replace the device with 'zpool replace'.

Answer 1

我也有类似的问题，这里。试试这个：

 zpool detach syspool c0t12d1  

它将踢出故障磁盘，然后您的池将再次在线。

Answer 2

• 驱动失败了。
• 备用的取代了。
• 您可以替换失败的磁盘，重建可能取决于您的池autoreplace设置。

一些细节，如操作系统，发行和硬件涉及可能有助于一个更具体的答案。

一旦重建完成，备用的就会恢复到多余的职责。
