Dear Zuners, I have installed RDO pike. I stopped openstack-nova-compute service on one of the hosts, and installed a zun-compute service. Although all the services seems to be running ok on both controller and compute but when I do
openstack appcontainer service list It gives me following +----+--------------+-------------+-------+----------+-----------------+---------------------+-------------------+ | Id | Host | Binary | State | Disabled | Disabled Reason | Updated At | Availability Zone | +----+--------------+-------------+-------+----------+-----------------+---------------------+-------------------+ | 1 | node1.os.lab | zun-compute | down | False | None | 2018-06-20 13:14:31 | nova | +----+--------------+-------------+-------+----------+-----------------+---------------------+-------------------+ I have checked all ports in both directions they are open, including etcd ports and others. All services are running, only docker service has the warning message saying "failed to retrieve docker-runc version: exec: \"docker-runc\": executable file not found in $PATH". There is also a message at zun-compute "/usr/lib64/python2.7/site-packages/sqlalchemy/sql/default_comparator.py:161: SAWarning: The IN-predicate on "container.uuid" was invoked with an empty sequence. This results in a contradiction, which nonetheless can be expensive to evaluate. Consider alternative strategies for improved performance." Please guide... Regards, Muhammad Usman Awais
