This helped me, thank you!

I got this working now where HA OS is installed on the SD card and the NVMe drive is used as a data disk, per the official recommendation. Here’s what I did:

  1. Flash Raspberry Pi OS Lite 64-bit to my SD card, configure it to enable SSH prior to flashing.
  2. Install the SD card into the Raspberry Pil, which is installed in the Argon ONE V# NVME PCIE case along with a NVMe SSD.
  3. Boot into Raspberry Pi OS and the SSH into it once it’s up
  4. Run the relevant scripts for the Argon ONE V3 NVME PCIE (there are two of them listed in the instructions and they both require a reboot after executing).
  5. SSH back into the pi and confirm that the NVMe drive is available by running lsblk
  6. Take a look at /boot/firmware/config.txt, copy its contents somewhere for reference. The relevant entries were:
    dtparam=uart0=on
    dtparam=nvme
    dtparam=pciex1_gen=3
    max_usb_current=1
  7. Shutdown the pi, remove the SD card, flash with HA OS.
  8. Insert the SD card with HA OS, boot the pi
  9. Restore from HA OS backup (I’m migrating from an existing installation on a Pi 4, you could also just install from scratch)
  10. Enable SSH and I2C (I used GitHub - adamoutler/HassOSConfigurator: A set of Add-Ons to configure HassOS For various platforms and development purposes.)
  11. SSH into HA OS (the actual OS, not where you get with the Terminal addon)
  12. Edit to /mnt/boot/config.txt and add the 4 settings saved from earlier (step 6).
  13. Reboot.
  14. SSH into HA OS again, confirm NVMe drive is visible via lsblk
  15. Login to home assistant via browser, then go to Settings > System > Storage and Click “MOVE DATA DISK”, select your NVMe drive, and continue through the wizard to migrate most of the install to the NVMe drive.

For reference, I’m using a Western Digital 500GB WD Blue SN580 NVMe SSD, which is not on the list of compatible drives for the Argon ONE V3 NVME PCIE case, but seems to be working nonetheless.

I also installed this addon to configure the fan on the Argon case: GitHub - adamoutler/HassOSArgonOneAddon: A Home Assistant Addon for Argon One Fan Control.
