Blonde moment with zfs

[Johan Helsingius]

Can anyone explain this behavior:

# freebsd-version
11.1-RELEASE-p9

# mount | grep storage
zroot/home/storage on /usr/home/storage (zfs, local, noatime, nfsv4acls)
zroot/home/storage/backup on /usr/home/storage/backup (zfs, local,
noatime, nfsv4acls)

# df | grep storage
zroot/home/storage        21241268134 13341350980 7899917154  63%
 /usr/home/storage
zroot/home/storage/backup  8187760652   287843498 7899917154   4%
/usr/home/storage/backup

# ls /usr/home/storage/backup
ls: /usr/home/storage/backup: No such file or directory
