I want to move a cPanel server running on KVM to a new node. Disk type is raw:
Host max disk size: 300GB
Host actual disk size: 260GB
Real file usage on guest: 100GB
Transferring the whole backup over network takes around 3 hours and I don’t want to wait that long.
So, how to shrink the VM backup to the real file usage? I read https://pve.proxmox.com/wiki/Shrink_Qcow2_Disk_Files but this is not qcow2.
