Description of problem: python-redis is required by openstack-polling services to run. Right now it's not installed with director. excerpt from ceilometer-polling[14956]: verify_requirements, ceilometer-polling[14956]: File "/usr/lib/python2.7/site-packages/stevedore/named.py", line 123, in _load_one_plugin ceilometer-polling[14956]: verify_requirements, ceilometer-polling[14956]: File "/usr/lib/python2.7/site-packages/stevedore/extension.py", line 185, in _load_one_plugin ceilometer-polling[14956]: plugin = ep.load(require=verify_requirements) ceilometer-polling[14956]: File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2260, in load ceilometer-polling[14956]: entry = __import__(self.module_name, globals(),globals(), ['__name__']) ceilometer-polling[14956]: File "/usr/lib/python2.7/site-packages/tooz/drivers/redis.py", line 26, in <module> ceilometer-polling[14956]: import redis ceilometer-polling[14956]: ImportError: No module named redis Version-Release number of selected component (if applicable): openstack-ceilometer-api-5.0.0-1.el7ost.noarch openstack-ceilometer-central-5.0.0-1.el7ost.noarch openstack-ceilometer-common-5.0.0-1.el7ost.noarch openstack-ceilometer-compute-5.0.0-1.el7ost.noarch python-ceilometerclient-1.5.0-1.el7ost.noarch openstack-ceilometer-polling-5.0.0-1.el7ost.noarch openstack-ceilometer-collector-5.0.0-1.el7ost.noarch python-ceilometer-5.0.0-1.el7ost.noarch openstack-ceilometer-notification-5.0.0-1.el7ost.noarch openstack-ceilometer-alarm-5.0.0-1.el7ost.noarch rpm -qa | grep redis redis-2.8.21-1.el7ost.x86_64 Steps to Reproduce: Command used to deploy overcloud: openstack overcloud deploy --libvirt-type qemu --control-scale=3 --compute-scale=1 --ceph-storage-scale=0 -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml --templates --ntp-server <Server> Actual results: Traceback in log. Expected results: python-redis is installed
Eoghan, would you consider this as a dependency for ceilometer? If it is optional dependency only, it requires additional work in director (disk-image-builder at least) and this would probably miss OSP8 release.
Jaromir, yes python-redis is a dependency of tooz in the mode in which we recommend tooz is used for coordination between ceilometer central agents. Without tooz, then the central agent cannot be run in active/active mode.
Verified with openstack-tripleo-puppet-elements-0.0.4-1.el7ost.noarch. python-redis is installed and ceilometer-central is running on controllers.
