Simple 3 disk storage configuration for small home lab

[frickprox]

I'm not too knowledged in Linux voodoo.

I'm super overwhelmed by the storage options and opinions. Don't use ZFS on SSD, don't use LVM, don't use XFS. What should I use and how to config it?

I want to run small home lab with Home Assistant, Debian server for docker VMs (MQTT, influx, etc.) and small cloud NAS with FTP to record my 1 IP Camera.

I'm running on Lenovo M800 ThinkCentre with Pentium G4500 and 8 GB of RAM. My storage hardware is 120 GB SATA SSD and 2 × 500 GB SATA HDD. I don't need more storage, this is more than twice of what I'm thinking of using and it'd be hard to add more disks with M800 as there are no places to put the drives in.

I want to use 1 HDD for backups of the whole machine and 2nd HDD for camera recordings and NAS. All data will not be critical and want it to be easily restorable in case of failure.

I've created the PVE on SSD with 40 GB dedicated space that should be ext4 but PVE reports it as LVM in "Disks".

All setups I've seen are on somekind of expensive gear, with 20 CPU cores, 128 GB RAM and 10 disks. I want something simple and easy to maintain.

Don't use ZFS on SSD, don't use LVM, don't use XFS.

It always depends...
ZFS on SSDs is great, you just should get proper (enterprise) SSDs and not the cheap QLC consumer SSD crap.
LVM+LVM-Thin can be great for a single disk setup when you don'T care that much about your data or uptime (or when you got HW raid below it).
XFS could be useful in case you want to use qcow2 images.
