Home Asistant on Proxmox running ZFS Raid1 (lemmy.world)

I have just installed Proxmox 8.0.2 on my fanless PC over two identical 2TB SSDs and set-up ZFS RAID1 during install. Now I want to install homeassistant as a VM. I have created the VM, downloaded the Home Assistant qcow2 and transferred the qcow2 image to the /root of the Proxmox but don't know how I can link it to my HA VM. I saw that it is not a good idea to have qcow2 over ZFS especially in the case of SSD due to the higher wear of the SSDs so I was wondering what my options are.

I am also open to re-install Proxmox and change the drive setup. What's the best path ahead of me?

Sorry I can't help with the proxmox stuff but it is absolutely fine to have a qcow2 image on an SSD pool. Modern SSD write endurance is so high as to be a non issue especially in the relatively tiny work loads that HA will put on it

I think the problem is that ZFS expects zvols and qcow2 is adding an additional layer on top and this is increasing the wear and tear of the disks especially SSDs and eventually it is not recommended. Plus qcow2 I think is better for virtualisation.
