After what appeared to be a successful installation, I rebooted when prompted. Instead of the Unraid gui opening, I received an error that the site was unreachable. I logged into the IPMI interface on the server, and it showed Unraid was at the Tower Login, but no gui. I don't have a diagnostics log to share. I am willing to attempt the same process with my backup USB stick to see what happens, but if it fails, I would need help to get a log file out of it.
The good news, is I was able to rectify the situation by reflashing my USB drive with 6.6.7 and recopying the config back onto it.
- original version of Unraid on the server was 6.6.6
- data disks are encrypted
- Unraid Pro license
- 1 Parity disk
- 4 data disks
- 2 cache disks (not encrypted)
I upgraded my backup USB stick successfully, then re-inserted my primary USB stick with I flashed (above). Upon boot, I had a Tower login, but no Unraid GUI. A similar result to my upgrading experience. It's possible the upgrade was successful, but the failure of the GUI to start is the same between both situations.
