我在 Solaris 10 上有一個包含四個 raidz1 的池,其中三個如下所示:
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.

如果我看到重新同步已開始,但沒有磁碟標記為“離線”或“不可用”,這意味著什麼?從陣列中刪除其中一個磁碟是否安全?我應該用備用設備更換重新同步設備嗎?
答案1
有幾種解釋。其中之一是系統與磁碟失去聯繫一段時間,現在正在更新該磁碟的最新變更。
您不應在重新同步時刪除磁碟,因為 RAIDz1 僅具有單一磁碟容錯能力。
