OpenNebula keeps trying to bootstrap the database on top of the already existing database. Today our OpenNebula installation begin presenting authentication errors, I recreated the passwords for oneadmin and serveradmin but the problem persisted. After many hours of trial and error, now even the opennebula.service is refusing to start with the following error. I would like to add that recreating the database is not an option, as I will not start this installation over, I would rather migrate to another solution. ```auto Password file /var/lib/one//.one/sunstone_auth already exists but OpenNebula is boostraping the database.

This is a security check not to overwrite an existing DB by error. It seems that at some point the bootstrap process did not complete or an existing DB was not properly cleaned. Simply delete the file it complains about (it’ll be regenerated). You can remove all the auth files but the oneadmin password. Cheers! ---

I did that, it just recreates all the files and keeps giving me the same error.
