导入缺少一个未知 vdev_children 的 zpool。

导入缺少一个未知 vdev_children 的 zpool。

我的 raid-z zpool 处于降级模式，我使用以下命令在 zpool 中添加了一个新磁盘：

zpool add -f  uhuru-test da3

问题是 da3 被意外删除，现在系统不再看到 uhuru-test 池。

我在另一篇文章中看到，只需创建一个指向丢失设备的虚假链接即可恢复池，从而解决此问题。->zpool 导入时缺少缓存设备

我想知道是否有办法恢复我的 zpool，而不知道第二个丢失的 vdev_children（磁盘已被​​意外删除）。

但就我的情况而言，我不知道路径。是否可以找到该路径以应用相同的解决方法？

    devices and try again.
   see: http://illumos.org/msg/ZFS-8000-6X

    Additional devices are known to be part of this pool, though their
    exact configuration cannot be determined.

我曾尝试强制导入该池，但没有成功。

cannot import 'uhuru-test': one or more devices is currently unavailable
[root@freenas] ~# zpool import -Ff uhuru-test
cannot import 'uhuru-test': one or more devices is currently unavailable
[root@freenas] ~# zpool import -FfN uhuru-test
cannot import 'uhuru-test': one or more devices is currently unavailable
[root@freenas] ~# zpool import -fN uhuru-test

谢谢你的帮助，Nadj
