降级磁盘在重启后恢复在线状态

我的 FreeNAS 服务器 [版本 9.10.2-U1 (86c7ef5)] 中的 ZFS 卷上有一个降级磁盘，在尝试更换它之前，我重新启动了服务器。

以下是什么意思？我的磁盘有问题吗？

  • 在启动时，即使所有磁盘的卷状态均已恢复在线，我仍会收到以下信息：警报

  • 在清理操作期间，新的警报显示磁盘处于降级状态，校验和为 670（不确定这意味着什么）：磁盘降级新警报

  • 擦洗结果： 
    The scrub operation is now finished. Here are the final results:

     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'.

正如输出所示smartctl -a，驱动器报告了板载测试的读取错误。这排除了 RAID 控制器或软件问题。

这真是太糟了。尽快找到新的驱动器并更换它。错误可能是暂时的，因为它似乎发生在磁盘上的同一物理位置附近 - FreeNAS/zfs 可能不会再次访问该确切位置，直到您发出清除命令并告诉它检查整个卷，这就是驱动器在下次启动时重新上线的原因。
