trutz, that method uses a non-hassos system, which is very different when it comes to usb boot.
A quick update on my progress:
So far my initial experiments have been successful. This is with a pi3b+, startech usb3.1 to SATA3 adapter cable, and a Kingston 120GB ssd drive, using the above mentioned dev image for rpi usb boot. Just flashing that image to the ssd and plugging it in, hassos boots and reboots just fine. Next I’m going to play with restoring a snapshot and see how it behaves with everything working.
On a side note, hope someone can help me on this OT matter… When flashing a hassio image to a larger ssd (larger than 2GB I think) the system is not recognizing and therefore not using all the extra space. I tried to fix this with gparted… when I open gparted it warns me that it needs to ‘fix’ the mbr so it can use the unallocated space. I click yes twice, then it opens the gui. Then I resize the data partition to fill out the rest of the room and hit apply. All seems to work fine (all files and file sizes look correct), but when I do this it doesn’t boot up. There must be something I’m doing wrong; I figure it must be possible to increase the size of the data partition without screwing it up otherwise. Any advice/suggestions on how to ‘expand’ the data partition in this case?
[edit: Exciting update… the snapshot restore worked and now my no-sd card hassos system is humming along well. WOOT!!! …now I just need to make the data partition bigger so I can record 90days of data. :D!]
Look ma’, no drives, LOL! Weird how the ssd isn’t showing up in the hardware gui. If you look close, you can see the edge where it says HassOS 3.4… woot! :D!
