Comment 40 for bug 1560965

Hi,

I am a newbie to Openstack and I am setting up a lab environment using Openstack-ansible (OSA)for deployment of Pike. I am not sure if what I am running into is related to this bug. I originally thought I was hitting an iscsi issue, but as I went through this thread, it seems to be related.

On initial deploy, I was able to spin up a new instances from image. However things stopped working. The only thing I can think of is something was updated during OSA redeployment.

Some of what I am seeing in the nova-compute log are as follows:

The task would die and I would get a host not found error in horizon. I tried using the patch in 20 as well as eblocks update above, and neither worked. I saw the js file at 2 locations for horizons:

/openstack/venvs/horizon-16.0.8/lib/python2.7/site-packages/openstack_dashboard/dashboards/project/static/dashboard/project/workflow/launch-instance/launch-instance-model.service.js
/openstack/venvs/horizon-16.0.8/lib/python2.7/site-packages/static/dashboard/project/workflow/launch-instance/launch-instance-model.service.js

I would be grateful for any help.

Thanks
David
