Understanding Proxmox Storage: local vs local-lvm

With the default Proxmox setup, local stores the ISO images and container templates, and local-lvm stores the installed VMs and containers themselves. I would not recommend deleting local-lvm in order to resize local. That removes the ability to take snapshots of each VM and container, which is one of the most beneficial reasons to use a Type 1 hypervisor in the first place.
