无法导入已导出的池。
根据以下信息，我是否能够以某种方式导入池？或者，是否有办法从驱动器本身检索数据？
两个磁盘均无损坏。
Solaris 11.3
# zpool upgrade -v
This system is currently running ZFS pool version 37.
# zpool import
no pools available to import
我尝试了各种标志：-a，，-d... -f，但仍然无法导入池。
如果我运行# zdb -l /dev/dsk/c2d1它输出...

另外，可能会有用，请注意我已经从 media_pool 物理断开了第二个镜像驱动器的连接。（导入对 Live CD 或原始安装上的两个驱动器都不起作用）。

答案1
以下答案是一种解决方法。正确答案应该解决为什么zpool import尽管 zbd 拾取了 LABEL 0，但无法正确“读取”它，却无法正确导入池。
一切还没有丢失。取出一个镜像驱动器并将其粘贴到另一台机器上，从 Solaris 11.3 LiveCD（或至少具有类似 zfs 版本的操作系统版本）启动。
zpool import media_pool在另一个盒子上成功了。现在导出它。
zpool export media_pool
在原始机器上清除 /etc/zfs/zpool.cache。关机。移除第二个镜像驱动器。插入原始镜像驱动器（从上一步导出到不同机器上的驱动器）。重启机器并导入池。
