如果当前池是根池，如何将新磁盘添加到 ZFS 并使其可用于现有安装点？

Question

我的 S11 服务器有以下配置：

磁盘 #1 用于 rpool，这是我想添加磁盘 #2 以增加已安装文件夹可用大小的根池，但我无法将磁盘添加到现有 rpool，因为它是根池。

有没有办法让新磁盘可用于“/”文件夹？是我创建新 zpool 并将其安装在新文件夹下的唯一选择吗？

谢谢。

         still be used, but some features are unavailable.

附加第二个磁盘作为第一个磁盘的镜像，等待重新同步，移除第一个磁盘，将属性设置为自动扩展。不要忘记设置启动代码或类似的东西。例子：

zpool attach rpool olddisk newdisk
...wait, check using zpool status rpool
zpool detach rpool olddisk
zpool set autoexpand=on rpool
