When you have got the hang of your new setup, look for the “Proxmox VE” integration - you can expose stats from proxmox to HA and keep an eye on them, including things like the usage of local-lvm… you don’t want that to fill up, because you will get all kinds of weird errors on the HA database if that happens, as I found out when I was playing around after switching to proxmox on a pc a few weeks ago. In particular, leaving lots of snapshots lying around can increase the amount of disk used considerably. So experiment with them (it’s a great feature) but don’t leave them if you don’t need them.
