I've uploaded a patch to fix the ZFS portion of mkfs.lustre and tunefs.lustre.

Peter,

Per Nate "There's an issue with ZFS code that doesn't call initial load of hostid (SPL::zone_gethostid()) until creation or importation of a pool."

So this is still an issue even after adding hostid in node provisioning

As I understand it, this issue is going to be handled in a DCO ticket

After Minh's comment above I retested and the testing could still not continue. Throwing the following error message:
