断电后 ZFS 池变得非常混乱

发生硬断电和 UPS 故障后，ZFS 池处于我无法理解的状态：

$ zpool status -c serial
  pool: storage
 state: DEGRADED
status: One or more devices could not be used because the label is missing or
        invalid.  Sufficient replicas exist for the pool to continue
        functioning in a degraded state.
action: Replace the device using 'zpool replace'.

上述状态有很多我不明白的地方：

1. 所有故障磁盘都具有与某个在线磁盘相同的序列号
2. UNAVAIL 磁盘序列号是我用于缓存的两个 SSD 之一的序列号，而不是用于池的 HDD 之一的序列号
3. 两个故障缓存磁盘的序列号是两个存储硬盘的序列号

是什么原因导致池容量在这种状态下减少？池容量还能恢复吗？我考虑过尝试这里描述的步骤，但我甚至搞不清楚哪些磁盘出了问题。这篇文章描述的简单步骤能解决我的情况吗？我真的很需要帮助，先行感谢。
