They report like this .. imb@toshi:/home/imb> uname -a FreeBSD toshi.auburn.protected-networks.net 14.0-CURRENT FreeBSD 14.0-CURRENT #25 main-eb61de5b78: Fri Jan 22 10:03:02 EST 2021 root@toshi.auburn.protected-networks.net:/usr/obj/usr/src/amd64.amd64/sys/TOSHI amd64 imb@toshi:/home/imb> 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(5) for details. Is it safe to upgrade the root pool? imb
