This week, I reconfigured my Lincstation N1 with Proxmox and HexOS in a VM. This is a temporary test setup, mainly to experiment with NVMe passthrough. Spoiler alert 😊: It works! For over a year, I had TrueNAS running on it, and that worked perfectly fine as well. Lincstation N2 – My Future Setup I backed the Lincstation N2 on Kickstarter. With the 30% early bird discount, it costs $309 / €329. 🔗 Kickstarter Link Eventually, I’ll use the N2 for my final setup, while the N1 will become my Proxmox Backup Server. Lincstation N1 – Specs Intel Celeron N5105 (4 cores) 16GB RAM 128GB ROM (not used) 2× 2.5" SATA bays (2× 500GB Samsung 870 EVO SSDs) 4× PCIe M.2 2280 slots (4× 2TB Samsung SSDs) 2.5GbE NIC Installation Steps – Proxmox & HexOS (NVMe Passthrough) 1️⃣ Install Proxmox Download the latest Proxmox ISO and create a bootable USB using Rufus. Boot from USB and install Proxmox. Installed on two 500GB SSDs (btrfs mirror setup). After installation, access Proxmox via the web interface. Run some post-install steps: Post-install helper script: 🔗 Proxmox Post-Install Script Install the latest Proxmox updates. 2️⃣ Install HexOS in a VM (NVMe Passthrough Setup) Download HexOS ISO and upload it to Proxmox. Create NVMe passthrough mappings: In Datacenter → Resource Manager, create 4 NVMe mappings (NVME1, NVME2, NVME3, NVME4). Create a new VM: BIOS: SeaBIOS Disk: 50GB HDD RAM: 8GB CPU: 2 cores (host) Network: Virtio CD/DVD: Connect the HexOS ISO (At this stage, do not attach the NVMe SSDs yet.) Boot the VM and complete the HexOS installation. Shutdown the VM. Attach NVMe SSDs: In the hardware tab, add the 4 NVMe SSDs as PCI devices. Boot HexOS again: If everything is correct, HexOS should detect all 4 SSDs, allowing you to create a storage pool. Done! 🎉 Special thanks to @Dylan and @PsychoWardsfor encouraging me to share more about my homelab! 🚀 Also a picture of my N1. It's fits perfectly in my 10 inch rack. (BTW, the other device is a NUC 11 pro)

If you can still afford to wipe your drives, you can setup RaidZ2 in Truenas.

No, you cannot change from a RaidZ1 to a RaidZ2, this is defined once during the creation of the pool, but changing it requires to destroy and recreate the pool with RaidZ2, which will wipe all the data from the disks. If you want to have a RaidZ2 you either need to wait until Hexos supports it or create it manually in truenas and live with possible side effects in Hexos or ditch Hexos for the time being and switch to a truenas installation and migrate back to Hexos once pool migration because available some time after version 1.0.

I just installed and started setup. Same position. I have 5 drives and it's forcing Raid 5, which no option for manual configuration.
