Hi,
It sounds like you are trying to bootstrap multiple times because the first time failed for some reason. The bootstrap process assumes a pristine database with nothing in it so running it again will not work unless the broken database is dropped and recreated first.
But this situation should never occur. It would be helpful if you could post the first error you got that made you retry to initialize the database and include the contents of /etc/qlustar/qluman/installsettings. The later file would let us run the installer with the same option you selected so we can reproduce the problem and fix it.
