I've been using ZFS for a few years now, pools, datasets, and sparsebundles on them.
I've seldom seen mentioned "HFS formatted ZVOL On ZFS" (like here > https://openzfsonosx.org/wiki/FAQ#Q.29_Can_Time_Machine_backups_be_stored_on_ZFS.3F) but I don't get the procedure and can't find any info about it, anywhere included on this forum or on the FAQ.
So,
1) do I still have to start with the regular "sudo zpool create..." and then format the pool with Disk Utility? Or is it a different secret procedure?
2) then, must I fear any issue with an already partitioned disk with mixed HFS and ZFS partitions/pools on it? (or is it possible at all?)
3) is there any benefit compared to a sparsebundle on a ZFS volume?
Thanks for any clarification.
