I don't see any obvious errors in the cinder logs.

Looking at https://bugzilla.redhat.com/show_bug.cgi?id=1383899 which was the reason for the test addition to Cinder, it seems like it has something to do with making osprofiler enabled more than the actual volume backend.

[Matt Riedemann (mriedem)]

osprofiler is not enabled in the ceph CI job:

So I'm not sure why this would still fail.

Seeing this with Oracle ZFSSA CI too. Haven't tried to really dig into it too much yet. e.g. https://openstackci.oracle.com/zfssa_ci/refs-changes-44-526344-1-iscsi/testr_results.html
