ZFS 按 ID 导入池，因为名称已存在

我的原始系统无法启动。有很多错误我无法解决。我在新设备上安装了 ubuntu，可以从旧磁盘看到旧池。

我无法导入这些池，因为它们有相同的名称。我该如何导入 rpool？

~$ zpool status
  pool: bpool
 state: ONLINE
config:

        NAME                                    STATE     READ WRITE CKSUM
        bpool                                   ONLINE       0     0     0

$ sudo zpool import
   pool: bpool
     id: 13370236194316687362
  state: ONLINE
status: Some supported features are not enabled on the pool.
        (Note that they may be intentionally disabled if the
        'compatibility' property is set.)
 action: The pool can be imported using its name or numeric identifier, though
        some features will not be available without an explicit 'zpool upgrade'.

您可以通过新名称下的 id 导入池，将其导入到某个备用根目录也是明智之举：

zpool import -o altroot=/oldrpool 8969077933931556505 oldrpool
