Hi Neil,
thanks for your quick and direct feedback and please excuse my incautiousness. Being a software developer, I am still new to admin stuff and don't have much experience in hosting servers.
The "flush" command is documented in the help text of "lava-server manage". From the information there it seemed as if "lava-server manage dumpdata" would create a dump of the database (which it did) and that I might be able to restore it with "lava-server manage loaddata" (which I couldn't) if the flush would not do what I expected.
However, the database in that installation was not important at all, I spent some time experimenting with LAVA on this machine and just wanted to have a clean database for starting production use. I assumed there should be an easy way to achieve this.
With your help, I was able to reset my LAVA database using the following commands:
sudo apt-get purge lava-server sudo rm -rf /etc/lava-server/ sudo rm -rf /var/lib/lava-server/ sudo pg_dropcluster 9.6 main --stop sudo pg_createcluster 9.6 main --start sudo apt-get install lava-server
Thanks for pointing me to the backup topic, I will address that in my next step.
Cheers, Tim
