Hi Aaron,

What I did for reset the database was:

---
# pwd

I am in doubt because the service got up but it didn't create the database.
Is it right?

Thanks,

Hey Murilo,

When you deleted the /var/lib/perfsonar/topology_service contents, you had
reset the database. This is just loading new data into it if desired.

Cheers,
Aaron
