My raid-z zpool was in degraded mode, I have added a new disk in the zpool with the command:
zpool add -f uhuru-test da3
The problem is that da3 have been accidentaly erased and now uhuru-test pool is not anymore seen by the system.
I have seen in another post that it is possible to get around this problem by simply creating a fake link to the missing device in order to restor the pool.-> zpool import with missing cache device
I would like to know if there's a way to restor my zpool without knowing the seconde missing vdev_children (The disk has been erased accidentaly).
But in my case here, I don't know the path. Is it possible to find that path in order to apply the same workaround ?

Additional devices are known to be part of this pool, though their
exact configuration cannot be determined.
I have tried to force to import the pool but without success.

Thanks for you help, Nadj
