我维护一台带有 ZFS 存储池 (RAID Z3) 的 Debian 服务器。最近 ZFS 报告两个磁盘同时发生故障：
ZFS has detected that a device was removed.

生成这些消息后，热备用已激活并立即开始重新同步。重新同步后池的状态如下：

磁盘d0-part1似乎d1-part1已连接并且工作正常。
这是由于与磁盘降级无关的因素造成的错误吗？两个工作磁盘同时发生故障似乎不太可能。停用热备件是否安全？
答案1
磁盘断开似乎是由电源问题引起的。升级机器的 UPS 后，我没有遇到任何问题。我停用了热备件
zpool detach datapool hs-d0-part1
然后我重新银化了泳池
zpool scrud datapool
将池恢复到原始状态。
