Ok. Not sure if this is supposed to work, but what if you create a ZFS
Volume (zfs create -V 100G rpool/lvm) and make that a PV (pvcreate
/dev/zvol/rpool/lvm) and make a VG (vgcreate pve /dev/zvol/rpool/lvm)
and then a LV (lvcreate -L100% pve/data) ? Does that allow you to use

(Not 100% sure about the commands, check before executing)
