No, not stuck, came back after a while:
zpool status -v BACKUP00
pool: BACKUP00
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.
scan: none requested
config:
NAME STATE READ WRITE CKSUM
BACKUP00 ONLINE 0 0 0
ada3p1 ONLINE 0 0 0
errors: No known data errors
[...]
zfs list -r BACKUP00
NAME USED AVAIL REFER MOUNTPOINT
BACKUP00 1.48T 1.19T 144K /BACKUP00
BACKUP00/backup 1.47T 1.19T 1.47T /backup
