Hi, just upgraded from Mitaka to Newton and Ubuntu 16.04 and now getting a python error for cinder-volume.

# /etc/init.d/cinder-volume systemd-start
Traceback (most recent call last):
  File "/usr/bin/cinder-volume", line 6, in <module>
    from cinder.cmd.volume import main
  File "/usr/lib/python2.7/dist-packages/cinder/cmd/", line 39, in <module>
    from oslo_privsep import priv_context

  File "/usr/lib/python2.7/dist-packages/oslo_privsep/", line 213, in <module>
    def _fd_logger(level=logging.WARN):
AttributeError: 'module' object has no attribute 'WARN'

Any idea why this is happening?

Do you see something suspicious? Unfortunately I dont have any other log, which is a little bit weird I think (or its the systemd way...)


removed all cinder and python packages for oslo. Now I am getting this:

Have you updated all packages in the node or just cinder?

updated all packages (dist-upgrade) and upgraded the openstack packages to newton

AFIK, this can be an issue with an oslo_log or oslo_privsep libraries.A quick look at the code, seems that libraries are correctly imported and used. Another issue may be a malformed option into cinder config files, check log_levels or debug

In the past, cinder packages had issues that config into /usr/share/cinder had precedence over options in /etc/cinder. Maybe the issue can come from there. Or an issue with the upgrade process. Upgraded python version?

Do you have other logs but systemd logs, the ones in /var/log/cinder? Also configuration files would be helpful if there is an error, or missed change something after upgrade. egrep ^[^#] /etc/cinder/<file>
