Proxmox Install (SDD & NVME)

[Dataninja]

I'm newer to Proxmox and have been educating myself through Youtube university and I think I may have incorrectly setup my install. Before I get too far into setting up VMs and LXCs, I'm seeking some guidance.
Current config:

• Mini pc - Intel 12650H, 64gb of Ram
• 1 tb SSD -Proxmox install
• 2 tb NVME in ZFS for VM and LXC
• Qnap NAS (30tb) available through ZFS share

Should I have installed the Proxmox OS on the NVME? Should I be avoiding ZFS on the NVME for single disk? I got the idea from a couple of posts on reddit.

1TB SD fpr PVE is a bit of wasted space, as 16-32GB would be fine for the PVE. More space is only useful in case you want to store a lot of backups/ISOs/templates/virtual disks there. But if you want to use that for backups keep in mind that you would need to backup your /etc folder to another storage like your NAS. And the system disk doesn`t need to be fast. Even a HDD would do the job. So NVMe performance isn't required.

If ZFS on a single disk makes sense depends...
The SSD will probably be slower and die sooner with ZFS but you get some nice ZFS features like bit rot detection (not bit rot protection, for that you would need more disks), block level compression, replication, snapshots, encryption, quotas and so on. If you don'T care about those features a LVM-Thin might be a better choice.

Thanks for the info. It was a spare 1 tb sdd and had no other use for it at the moment.

When you say die faster. How fast are we talking? Like within a year or two? If so, since I've only setup Plex and docker vm, I guess I don't mind going back and redoing it all over again. Do NFS shares play nice with VMs installed on LVM-Thin volumes?

Really depends on the workload. But I wouldn't wonder if that SSD is wearing 2 or 3 times faster with ZFS compared to LVM-Thin.
