I got omv on my raspberry pi 3 (yes I know it will be slow but I want to try it). I boots properly but when it asks for raspberrypi login I enter admin then it asks for password, I enter openmediavault. It then gives me system information (ip, cpu temp, up time, etc). Under that it says:
No directory, logging in with HOME=/
This account is currently not available.
It then goes back to the login so I can't install it or get to the command part to set it up.
If I try the wrong username and/or password it say login incorrect like it should.
