There's many threads about this already on the forum, use the search bar in the top right. One example for ZFS: https://forum.proxmox.com/threads/decrease-size-of-vm-hard-disk.76293/ (not mentioned in there is that you need to shrink the partition (table) from inside the guest first!) Do note however, that this is not a fully supported operation for a reason, and *can* lead to data-loss if you don't know what you're doing. Last edited: Jun 23, 2021
