我有一个由 8 个镜像驱动器和一个热备用驱动器组成的池。镜像集中的其中一个驱动器发生故障，但我不知道热备用驱动器是否自动添加。备用驱动器的状态为“正在使用”，扫描显示它已重新镀银 1.7T。但是，镜像 0 仍然显示为“降级”。镜像 0 是否已 100% 启动，我只需使用“zpool clear primary_vol”清除状态？或者我需要发出“zpool replace c0t12d1 c0t21d1”
zpool status
pool: primary_vol
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
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'.

答案1
答案2
- 驅動器出故障。
- 备用电源接管了。
- 您可以替换故障磁盘，重建可能取决于您的池
autoreplace设置。
所涉及的操作系统、发行版和硬件等一些细节可能有助于给出更具体的答案。
一旦重建完成，备用发动机将恢复备用职责。
