I'm trying to install Proxmox 5.1 onto a server with a SATA SSD on it. (It also has a M.2 NVMe drive as well). However, the installation is error-ing out when it gets to the first step of creating partitions, with the error message: unable to create volume group 'pve'. If I press Ctrl + Alt + F2, and go to the console, I see an error message about "A volume group called pve already exists": It's possible this is from a previous failed PVE installation? Is there some way of using the Proxmox install media or installation wizard to wipe those disks and start again? (I didn't see an option to wipe/format disks in the installation wizard).
