我在 Solaris 10 上有一个由四个 raidz1 组成的池,其中三个如下所示:
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启动,尽管没有磁盘被标记为 OFFLINE 或 UNAVAIL,这意味着什么?从阵列中移除其中一个磁盘是否安全?我是否应该用备用设备替换重新同步设备?
答案1
有几种解释。其中一种是系统暂时与磁盘失去联系,现在正在更新该磁盘的最新更改。
您不应在重新镀银时移除磁盘,因为 RAIDz1 仅具有单个磁盘容错功能。
