I changed my Pi installation from an external USB SSD to an internal M.2 SSD inside the Argon One case (only attached the new bottom). I installed a new HassOS 5.10 and restored a snapshot.
Then I installed your Addon, booted two times and everything is working fine!
Great work! Thank you very much!
I added support for Raspian over the weekend. Should be fully supported.
Hi,
I get the following log after each reboot. Is that normal? What is this “Are you root?” thing?
Thanx
....
I don't see I2C.
mount: permission denied (are you root?)
no sda1 config found
no sdb1 available
no mmcblk0p1 available
This Configurator did it's job. Perform a hard-power-off reboot now.
You will need to reboot twice total, once to place the files, and again to activate the I2C.

Looks like it tried to mount and could not. You can remove this add-on. It’s not needed anymore.
Update to 0.11 and disable protection mode. This is what you should see with protection mode disabled
I decided to let it try anyway instead of just stopping because I find it more useful.
Due to changes in APIs, you must now disable protection mode. We can no longer mount partitions with access to a device. Protection mode must be disabled to mount a partition.
Looks like they wanted to stop the shenanigans of getting 5 points of security on an add-on which performs dangerous tasks… 
On the plus side, I was able to ditch device, and privileges, netting this add-on a whole 2-extra points of security.
I get the following error as a popup when I try to start the add-on. Any ideas?

Hi,
thanks for the immediate response and fix! Argonone active cooling works like a charm. You just saved me from going Karen.
BTW, do you know how to activate auto power on argon one after power cut and restore?
What platform are you using?
The V1 does not always have the capability.
Relevant email banter between myself and Argon Forty.

I can easily confuse myself with the different versions, but I believe this is just plain vanilla Home Assistant OS. No docker, no hassbian. just the standard downloaded image flashed onto an nvme m.2 SSD w/ a RPi4 8GB.
Fixed in v.11a
NVMe? Are you sure?
I’m positive. I’m booting using this SSD via USB. No microSD card inserted at all; that slot sits empty and unused.
Your I2C Addon v.11a update fixed the error message I saw previously and according to the logs, all went well this time around when trying to start it.
I then did the following, twice: sent the command “ha host shutdown,” then did a safe physical shutdown of the RPi4 and waited for the lights to go out, then unplugged the Rpi4’s power, replugged power, got back into HA (then did it again).
I then tried starting the ArgonOne Active Cooling addon, but noticed if I refreshed the add-on page it’d say it was stopped. Checking the logs, I see this:

Ah, Ok! I thought you are using the Argon One M.2 case. 
It’s a little bit overkill I think as the Pi will not work with the speed of the SSD.
Just migrated from sdcard to ssd drive with external HassOS boot. I’m also getting this error, the drive is connected to USB3.0, tested on both USB3.0 ports.

Edit: Using the official method works fine with the same SSD drive connected to the same USB3.0 port.
When did you update the addon? That was a problem for a few hours, about 24 hours ago, but should be fixed. I just uninstalled and reinstalled without any problems.
Migrated yesterday and i didn’t know about the add-on reload option so i guess was trying with the older version. Was not a big deal because the offical way worked fine. Thanks for the support!
Did you use the new HA> console method I added to the docs a few weeks ago?
