Can you try making a "zpool status -v" on core? Just to show how the pools are setup? My though is it might be using disk IDs instead of guids
No problem - The output is:
root@truenas:~ # zpool status -v
pool: VOL2
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.
