Hi guys. I am setting up OpenStack with Gnocchi with ceph as the storage backend, after service gnocchi-metricd start, it always reported "PermissionError: Failed to operate read op for oid measure", seems at the time metricd start, it tried to list the measure object, however, there is none such object, so does the permission show error? I didn't find any bug related, could anyone help to tell me what am I missing? Thanks.
