hole_birth ZFS feature = FreeNAS orphan?

FreeNAS 9.2.1 introduced hole_birth ZFS feature. Without doing enough research I upgraded my ZFS pool which enable this feature.

I haven't been able to find any other OS/NAS combo that my pool is now compatible with.

Have tried:
- ZFS on Linux
- NAS4Free
- OpenIndiana
- OmniOS
- NexentaStor
- Illumian

Anyone have any ideas? Otherwise I'll need to build a new pool (without this feature enabled) and port over to it.
