How can I change a ZFS mountpoint from legacy to be handled by ZFS

Currently using ZFS on ArchLinux. I have two datasets that I originally setup with legacy mountpoints: # zfs get mountpoint tank/data/home NAME PROPERTY VALUE SOURCE tank/data/home mountpoint legacy local # zfs get mountpoint tank/data/home/kevdog NAME PROPERTY VALUE SOURCE tank/data/home/kevdog mountpoint legacy local I have corresponding entries within /etc/fstab for these mountpoints I'd like to change these mounts to be handled by zfs rather than mount I logged in as root, and then did the following: umount /home/kevdog umount /home zfs set mountpoint=/home tank/data/home zfs set mountpoint=/home/kevdog tank/data/home/kevdog I went ahead and commented out the corresponding fstab entries for these mounts At this point I rebooted system however ran into a problem, the dataset tank/data/home/kevdog was mounted at /home/kevdog, however the directory was totally empty. After undoing what I just described above (setting legacy for management of these datasets) the /home/kevdog directory was no longer empty. Just curious to know why the process didn't work. Did I have to export/import pool again to make this work? Did I forget to do something else?
