i have zfs 3,86 TB. On this pool i have one vm
cat /etc/pve/qemu-server/102.conf
scsi0: zfs01:vm-102-disk-0,size=16G
scsi1: zfs01:vm-102-disk-1,size=2000G
scsi3: zfs01:vm-102-disk-3,size=800G
When I check the storage with cli, all is busy

I have a full storage on Proxmox all the time, when starting VM, ZFS01 checks for a long time
Why does it take up the whole if it is for the machine is only 2.8 TB? How to clean it?
zfs get all zfs01/vm-102-disk-1

It seems to me that the problem may be too small volblocksize. Can I change volblocksize for ZFS01/VM-102-Disk-1 don't lose data? If so, how? :)
