I’ve done this before with no luck. Was this after you had a working install on an SD card and then copied it to the USB drive? I have zero issues using USB drives with Raspbian but have never been able to get hass.io to boot even doing exactly as you said above. FWIW, that’s what I had to do after copying my existing HASS SD card to a USB stick.
Edit: let me try again. I’m almost certain I did this on all 4 files but I’ll try again. My next problem is getting my existing config working on hass.io but that’s for another thread lol
That is great news, will try as soon as I am near my RPI3 again. Thanks for sharing!
/edit
It is currently ‘Preparing Hass.io’, booted from USB drive with a fresh image and changes made as described above.
I could not get a (backup) image of my current SD card installation to work sadly, so we start over…
I burned a raspbian lite to my SD card, and enable USB boot mode
I burned hassio rpi3 image to my USB stick
try to boot with only USB device -> no boot
boot from SD card with USB stick is plugged in -> rasbian started
I changed the cmdline.txt on SD card and USB stick
boot from SD card with USB stick is plugged in -> resin OS started (but docker has an error)
I used ssh to see logs:
.............$ ssh root@pi -p 22222
root@hassio:~# docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
remove SD card and boot again -> resin OS and docker is running
root@hassio:~# journalctl -f

used gparted to increase the resin-data partion (I added ~1GB more space)
2.1 modified the files like instructed
connected the usb drive to rpi and bootted it up
Some challenges with debug ssh access thou. When trying to connect, I get following error:
Disconnected: No supported authentication methods available (server sent: publickey)
I have created a public key with putty and copied (id_rsa.pub) that to the root of resin-boot partition.
I now see in your post that you copied the key file itself to the resin-boot partition. You have to create a file called ’ authorized_keys’ there and paste the key in it.
Hi. I tried using gparted to increase resin-data (sda6) and it wouldn’t let me go beyond 1027Mb (from 1024) even though I had >11GB of unused space. Stuck now.
First you have to resize the main partition and after that you can increase the size of subpartitions. Some cases you have to even change the order of different subparttions but if remember right resin-data partition was the last subparttion. I hope this helps.
Are you sure that usb is mounted to sda? When I have multiple usb drives hooked to my rpi, every one is mounted to different path, like sdb, sdc, etc. This is just pure guessing…
Thanks but the other 5 partitions are all tiny so there is not much to steal from in order to make the data partition go from 1GB to say 2GB. I’m doing it with a gparted live USB drive under Windows.
With the modified thumb drive back in my PC, I added the following located in the resin-boot drive and also in the resin-rootA partition inside the resin-boot folder:
I changed the “root” option in cmdline.txt to: root=/dev/sda2
and I added the usb boot line below to config.txt, right at the end: program_usb_boot_mode=1
I then put the reworked thumb drive back in my Pi3 without the MicroSD card and after about 1 minute, the Home Assistant logo appeared so I knew we were underway. 20 mins later, working Hassio system with no MicroSD card. Yay.
@sanyatuning Your guide run only on a rip 3 on the 2, 1 or 0 you need always the sd card. So I think that rootwait param is necessary to wait until all usb devices is correctly recognized
