[Julien Danjou (jdanjou)]

This is very odd. The option is set but it cannot see it?

[fengchaoyang (fengchaoyang)]

Embarrassing, because i have a /opt/stack/gnocchi.conf file :(

[pablobrunetti (pablobrunetti)]

This error occurs because this file oslo_config/cfg.py does not get "opt" correctly from function _check_required_opts .

I have corrected this error using:

# chmod 777 /etc/gnocchi/*
