--- Comment #4 from Chloé Desoutter <chloe.desoutter at atasta.net> ---
Affects me aswell on 11-CURRENT. Run on a machine that had just panicked
before. Will panic when zfs set volsize=
root at cabron:~ # zpool status
pool: zroot
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(7) for details.
