这是我的情景：
我在带有2 x 500 GB SATA磁盘的服务器上安装了Ubuntu和native ZFS.我按照本指南安装了它：https://github.com/dajhorn/pkg-zfs/wiki/HOWTO-install-Ubuntu-to-a-Native-ZFS-Root-Filesystem
所以我在磁盘1上有一个16 MB的分区用于/ boot / grub和该磁盘的其余部分以及整个第二个驱动器专用于镜像zpool中的ZFS.一切正常.
问题是,现在我需要摆脱500 GB磁盘并将其更换为2 x 1.5 TB磁盘.
有什么方法可以将我的两个500 GB硬盘中的所有内容(数据,分区表等)复制到两个1.GB TB硬盘而无需从头开始重新安装系统？
我在这里添加@jlliagre请求的信息：

我一直在想：如果我从LiveCD启动,请按照installation guide到第4步(在我的新磁盘上分区并创建ZFS池),然后将新文件系统安装在/ mnt / new和旧文件系统上在/ mnt / old和rsync从旧到新？那有可能吗？或者它会搞砸一切？
