Grafana 503 error due to datasource

So I inherited a grafana environment due to some layoffs and as such after some maintenance last week our grafana environment is throwing a 503 error which seems to be due to a bad datasource(s). Since I can’t login to the interface I’d like to know if its possible to disable one or more datasources from the commandline temporarily so I can which datasource has the issue? I’ve looked in the logs, but they are NOT very helpful and are just showing:

Graphite encountered an unexpected error while handling your request.


Please contact your site administrator if the problem persists.

I’d like to get this back up and running. I’m seeing the following in
…/grafana/public/app/plugins/datasource directory
elasticsearch grafana grafana-live graphite mixed opentsdb

Anything would be helpful… thanks!
