[RDO-Manager][Heat] : get_file doesn't notice changes during update cause the first attempt of running 'openstack stack scale -r Compute-1 -n 2' to fail. Environment : -------------- [root@localhost ~]# rpm -qa | grep heat openstack-heat-engine-2015.1-dev829.el7.centos.noarch openstack-heat-templates-4643876-0.99.20150327.1822git.el7.centos.noarch heat-cfntools-1.2.8-2.el7.centos.noarch openstack-heat-common-2015.1-dev829.el7.centos.noarch openstack-heat-api-2015.1-dev829.el7.centos.noarch python-heatclient-0.3.0-post14.el7.centos.noarch openstack-tripleo-heat-templates-0.8.3-post32.el7.centos.noarch openstack-heat-api-cloudwatch-2015.1-dev829.el7.centos.noarch openstack-heat-api-cfn-2015.1-dev829.el7.centos.noarch Description : ------------- Due to a problem in heat "get_file doesn't notice changes during update" (see https://bugs.launchpad.net/heat/+bug/1445170) - when attempting to scale out nova-compute node after the overcloud is deployed - the command "openstack stack scale -r Compute-1 -n 2 " failed on the first attempt, but it pass on the second attempt. Steps to reproduce: -------------------- (1) Follow the steps to install undercloud and overcloud : https://repos.fedorapeople.org/repos/openstack-m/instack-undercloud/internal-html/ (2) Follow the steps to attempt to scale the number of compute node (In case the code already merged midstream just skip to step #3). git clone https://github.com/jprovaznik/tripleo-common git clone https://github.com/jprovaznik/python-rdomanager-oscplugin/tree/updates virtualenv ~/venv source ~/venv/bin/activate cd tripleo-common python setup.py install cd python-rdomanager-oscplugin python setup.py install run "openstack stack scale" (3) openstack stack scale -r Compute-1 -n 2 Results: --------- The command 'openstack stack scale -r Compute-1 -n 2 ' will fail when attempting to run it for the first time . Note: ----- The command will succeed when running it for the second time.
The fix made it in to the upstream 2015.1 (Kilo) release.
update fixed in version for full package name
No way to try and reproduce now with the exact command as the commands are outdated and will never be used. Running openstack overcloud update stack seems to work better (note that there were Tuskar bugs here, but those are out of scope).
