Hi all,

Does anyone know of the correct way to reduce a vm's boot disk size after it has been created and in use?
 
Depends on your underlying storage. 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.
