Zfs disk size.

Thank you. I read many articles but confiused. I enabled thin-provisioned on storage AFTER wm is created and used for some time. But it did not change anything. What must I check? Do I need to zerofill disk inside vm?
After the image (VM) creation you can't change it anymore.
Sorry I did not mention that; after I tried zerofilling this vm, I see its size 250GB but other wms are not same,
For example vm 113 has 50 GB limit and I can see the real usage in listing (20GB),
P2/vm-113-disk-1 20.8G 1.07T 20.4G -
So it seems like I need to zerofill or something?
