blasadmin reads the fileserver information from the database. In this case it seems no database details are configured for your current "default" deployment. You can verify by running:
blasadmin show data all
Maybe blasadmin needs to be executed against a different deployment (the -s flag allows this) or the DB info indeed needs to be configured on this system.
blasadmin -s _template show data conn
thanks bo duke,
i temp lost my connection to the database, i rebooted and im back in business. problem solved.
