Maybe it is language barrier. Given that you were complaining, I interpreted you calling the devs “geniuses” as intensely sarcastic and insulting their intelligence. I think most people would interpret that comment the same.
I like the idea of having the Host-OS on SD-card, and all the io on an external storage device.
Is this move persistent through Host-Updates?
How do you switch storage devices?
Is there any documentation on how to move the Data back to SD-Card?
So many questions,…
Maybe you found his post sarcastic. But wishing him to get no help actually places your response in a group of rude once. therefore violating forum rules.
Hi, did anyone else find their mDNS broke with the upgrade to 5? I was running 4, and all of my tasmota devices happily found the built-in MQTT broker. This was bullet-proof, and I could even change the system name and it would work from everywhere at the new name.local. Now, when I upgraded, every mqtt device in my house decided it couldn’t find Homeassistant anymore. They will find it by IP, but the .local naming space just doesn’t work. My PC will resolve it, and my router (Unifi ER-X) will ping the .local name, so it works at some level. The only thing I’ve changed is upgrading HomeAssistant (went from running a supervised 4 install on Raspberry Pi OS booting on SSD to a HassOS 5 install booting on SSD).
Yes I’m using a RPi 4
I followed the steps in the link below (even though I don’t have the 8GB version) when I moved to SSD and version 5.4 beta on my RPi 4. I think it’s important to be using the right USB to SSD adapter s mentioned in this post I linked below. A little hardware update and then yes, build home assistant on the SSD and restore the snapshot. But take a look at the link…
Mine seems to be working flawlessly. I’ve moved most of my smart devices to Tasmota (beta) integration and away from the MQTT integration.
Thanks for the info. I the tasmota integration still needs MQTT as I understand it, so it seems like that resolution is working for you…
Thats how it works, yes
‘Suddenly’ I seem to be running an unsupported OS and Systemd. Not a very cool message. All fine, but what am I supposed to do if you’re running 2020.12 on RPI with SD? A clean install and restore latest backup?
The reason we don’t advertise it is because it is just brittle in practice: It needs the right combination of SSD and SSD enclosure as well as RPi 4 firmware. The USB stack (and USB mass storage) is more complex than SD card enumeration, which in the end just leads to more cases where things can go wrong. And they do quite often: Just check the GitHub Home Assistant OS issue tracker, recently most issues stem from USB SSD boot… All this just make USB SSD boot not something we can recommend generally.
We certainly won’t break it on purpose, and address issues where possible. But we cannot make all combinations work… So if your combination works, that is fine! If it doesn’t then you should consider booting off SD card and use
datactl command to move just the data partition to the USB SSD drive.
Thank you for detailed and fair explanation.
I can agree with all your points, but I had (and I believe others too) a feeling HA team is heading official SSD boot support since OS 5.0beta. Since v5.8 and after your explanation it seems the team is stepping off this idea.
I currently boot from usb stick (rpi4) with rpi os. And ordered argon one m2 to boot from ssd. I was thinking about going to hassos, because I get “unsupported installation”, and wanted to do it “right”. But, from what I read here, Hassos isn’t ready yet. Booting RPI os from usb gives no problem at all.
Maybe go the RPI OS or Debian os way to boot from usb?
I have a Pi4 8gb, Argon One M.2 and a Kingston SSD A400 120GB M.2 (SA400M8/120G) running Home Assistant OS 5.6.
This setup has been working fine as far as I can tell.
I use a DHT22 temperature sensor using a rPi4 GPIO. It has worked fine for a while but upon installing OS 5.8 it broke. I am getting this message:

Guess you had 4.x OS before upgrading. 4.x OS is 32bit and supports GPIO, but 5.x is 64bit and doesn’t support Pi’s GPIO. Can’t understand why 5.8 was marked stable before fixing GPIO.
I really like the look of that case with the fan and the integrated SSD option!
How did you flash the Home Assistant OS to the M.2 Drive?
Does the power button still work when you are running HomeAssistant OS or do you have it set to Always On?
I have an RPI 3 with HassOS on a USB stick. No problems booting from USB stick.
But beware of the latest update of HassOS, version 5.8, my RPI got dns problems because of that, and have now downgraded to version 5.7. But booting from USB is no problem.
You’re lucky. I upgraded from 4.13 to 5.8 with a USB SSD and the upgrade bricked it. Downloaded a fresh 5.8 image and that would not boot from any of the USB drives I have, even with the latest bootcode.bin on an SD card.
I’ve reverted to 4.13 for now. I’ll have to read up on splitting the OS and data partitions. Shame I didn’t spot this in the release notes first.
I just received my argon on m2. So i can boot from SSD
My current setup boots from a USB stick with rpi os …
It’s an unsupported installation, says the supervisor… So, i was thinking that for my new install, i would use hassos, but, from what i read here, and other forum messages. I maybe better still use rpi os (of Debian?)
