Hi all,
previously i run a rasbian on a raspberry pi 3 b and home assistant from virtual enviroment, all installed on a external usb hd. The HD is a PiDrive of WD, this:
Now I have a new raspberry pi 3 b +, and I run hassio from sd card. Can I use a PiDrive instead of sd card???
Not with HassOS.
Noooo 
So for have more storage and also power I have to move hassio in somethink like nuc?
Not necessarily. It’s just HassOS won’t boot from a USB stick so you need something like Raspbian booting off USB and then a Docker install and then Hass.io as a generic Linux install instead of using HassOS which is provided here out-of-the-box with Hassio images.
Oooh OK, but I haven’t absolutely experience with docker… It’s difficult to install? There is some guide?
Wow tomorrow I’ll try! Thank you so much. I only have to do all this procedure on external hd…
You need to do a linux install on the hd and be able to boot from that then use dale’s script.
Dear DavidFW1960,
I made the docker installation as your suggestion. Now hassio is running without sd on my raspberry on the external 250GB hd. That’s great. All seems work, apart Grafana. I restore the previous setting but Grafana can reach the InfluxDB database, and give me this error:
Network Error: Bad Gateway(502)
But all the configuration is the same… I don’t understand why this happen, can you help me?
This is in Grafana log:
