Description Nir Magnezi 2014-02-04 16:29:05 UTC

Description of problem:
=======================
Found when I tried to verify bug #1061055
neutron-dhcp-agent won't start due to a missing import of module named stevedore.
installed the neutron-dhcp-agent on a dedicated node which only populates that service.

Version-Release number of selected component (if applicable):
=============================================================
openstack-neutron-2014.1-0.4.b2.el6.noarch

How reproducible:
=================
2/2

Steps to Reproduce:
===================
1. Install RDO on RHEL6.5 , allocate a dedicated node to host the neutron-dhcp service.
2.

Actual results:
===============

# service neutron-dhcp-agent status
neutron-dhcp-agent dead but pid file exists

# /usr/bin/python /usr/bin/neutron-dhcp-agent --log-file /var/log/neutron/dhcp-agent.log --config-file /usr/share/neutron/neutron-dist.conf --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/dhcp_agent.ini
Traceback (most recent call last):
  File "/usr/bin/neutron-dhcp-agent", line 6, in <module>
    from neutron.agent.dhcp_agent import main

  File "/usr/lib/python2.6/site-packages/neutron/manager.py", line 28, in <module>
    from stevedore import driver
ImportError: No module named stevedore

Expected results:
=================
service should be running.

Additional info:
================
workaround: pip install stevedore

Comment 1 Lars Kellogg-Stedman 2014-02-04 17:32:02 UTC

The missing stevedore requirement also prevents neutron-db-manage from running, which prevents a successful install via packstack.

The workaround should probably be "yum install python-stevedore" (using "pip" may get you a version of stevedore different from that available via packacges, which could result in new problems or masking ones in the package).

Comment 3 Assaf Muller 2016-01-04 17:42:09 UTC

I can confirm that RDO 5 on RHEL 6 has "stevedore" as required in its spec file. Closing as the 'ON_QA' stage is not relevant for RDO.
