zpool 顯示超出應有的儲存空間
我剛剛在 raidz1 中使用 3 個 HGST 6TB 驅動器擴展了我的 zpool 命名儲存。我認為這只會增加大約 11.x TB 的儲存空間（因為它們實際上是 6000GB 驅動器）但是現在 zpool list 顯示我總共有 27.1 TB。這似乎比我應該擁有的更多。我很害怕我做錯了什麼，我的家庭伺服器陣列失去了奇偶性。我將它們添加到池中
sudo zpool add -f storage raidz1 drive1 drive2 drive3
我是否做錯了什麼？如果有，是否可以恢復我的更改？

不好了！你做了一件很糟糕的事…

需要注意的兩個問題：
在 RAIDZ1|2|3 下，該
zpool命令反映組成池的磁碟大小，包括奇偶校驗。zfs list將顯示可用空間。這就是差異的來源。此外，您最終做的是…通過添加 3 個磁碟的 RAIDZ1 組來擴展 4 磁碟 RAID 1+0（ZFS 鏡像）。
因此，您的鏡像意味著 RAID1 對被條帶化在一起。美好的。但是通過添加一個 RAIDZ1 組，您現在擁有一個跨兩個鏡像集和一個 RAIDZ1 的條帶。
鏡像組中的兩個磁碟或 RAIDZ1 組中的兩個磁碟發生故障將導致池完全故障。
您應該通過創建更多鏡像對添加偶數個磁碟。現在，您無法恢復更改，因為您的數據分散在磁碟組中。這可能是一種備份.重建.恢復的情況。
