No, volumes seems have all refreservation to 'none', as expected; current
situation is:
root@lamprologus:~# zfs list | grep ^rpool-data
rpool-data 54.2T 3.84T 171K /rpool-data
rpool-data/vm-100-disk-0 1.11T 3.84T 1.11T -

rpool-data/vm-100-disk-9 2.11T 3.84T 2.11T -
and a random volume (but all are similar):
root@lamprologus:~# zfs get all rpool-data/vm-100-disk-18 | grep refreservation
rpool-data/vm-100-disk-18 refreservation none default
rpool-data/vm-100-disk-18 usedbyrefreservation 0B -
Another strange thing is that all are 2TB volumes:
root@lamprologus:~# cat /etc/pve/qemu-server/100.conf | grep vm-100-disk-19
scsi20: rpool-data:vm-100-disk-19,backup=0,discard=on,replicate=0,size=2000G
but:
root@lamprologus:~# zfs list rpool-data/vm-100-disk-19
NAME USED AVAIL REFER MOUNTPOINT
rpool-data/vm-100-disk-19 3.40T 3.84T 3.40T -
why 'USED' is 3.40T?
Thanks.
