ZFS:如果所有磁盘都处于在线状态但进行了重新镀银,这意味着什么?

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.
action: Wait for the resilver to complete.
 scan: resilver in progress since Wed Jun 17 16:46:31 2015
    536G scanned out of 43.9T at 389M/s, 32h26m to go
    536G scanned out of 43.9T at 389M/s, 32h26m to go
    27.3G resilvered, 1.19% done

    spares
      c0t600C0FF00012FBB11555EC5401000000d0    AVAIL   

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。
