I thought I would try again even though last time it trashed my Odroid system, wouldn’t boot, and I needed to reinstall HAOS from scratch.
I took a lot of precautions, shut down the system completely. Formatted fresh my Samsung nvme with ext4, did a backup of course, plugged the nvme into a powered USB hub, rebooted and then executed the move data disk function from the menus.
The NVMe drive was recognized which was good.
After about 10 minutes it seems to have rebooted, I wasn’t sure at this point if it had actually finished as it still showed the 50% and the emmc life at 10% on screen. No on-screen FINISHED message, perhaps that needs looking at. I waited another 20 minutes just to be safe.
Then I held my breath, went Settings → System → Storage and it now shows 3% used with no progress bar at all for estimated life. Success!
But…some of the sidebar items didn’t load on the dashboard so I did a full shutdown/reboot and the system didn’t respond at all. Wouldn’t boot.
I stuck the nvme USB connector into my Linux machine and it looked like the data had been copied successfully, yet the system wouldn’t boot.
I tried every combination for rebooting, with the nvme in, without, putting the nvme in while it was booting etc.
And after about five times lo and behold the system came up, it seems to be working and only 3% showing used. All functions working, and seems more responsive to sensor detection functions.
I’m very happy to have a more robust faster system where I don’t worry about running out of space on the 32GB emmc.
Perhaps when I did it last week and it failed, it would have worked if I’d been more persistent just trying to reboot again and again.
