2015-04-21 07:17:54 -0500 answered a question neutron namespaces not created in all cluster nodes

Ok i have solved my issue. The thing was that although qdhcp namespaces exist and are "copied" via the cluster the router namespaces do not. Due to the problem i had faced (power issues with controllers) some of the qrouter namespaces did not "switch" L3 agent and they remained on ones that did not run. I transfered the qrouter namespaces on the running L3 agent and they work fine now.

Thanks for taking the time to answer my question Omar.

2015-04-16 07:39:10 -0500 asked a question neutron namespaces not created in all cluster nodes

Dear all, i am facing a serious issue with my openstack setup. I am running openstack Icehouse on Ubuntu 12.0.4.1 and used Mirantis Fuel 5.1.1 to deploy. I have a HA architecture with three controllers/network nodes. Moreover i am using one L3 agent to run two external networks. The above setup was working well for some months now when suddenly some of my users complained that they cannot access their VM's from the internet (via floating IP).

Debugging the problem i found out that not all of my namespaces are created on all of my network/controller nodes. For example i have node-1, node-2 and node-3. When the L3 agent runs on either node-2 or node-3 only one qrouter namespace is created/loaded, when the L3 agent runs on node-1 i have 19 q router namespaces. Same goes for the qdhcp namespaces. When they run on node-1 and node-3 i have 25 qdhcp namespaces. Node-2 loads only 1.

I checked the mysql tables and all networks and routers are on all nodes. Has anybody else faced something like this?? I am in desperate need for help:)

2015-01-04 08:46:14 -0500 answered a question Apply patch to nova

Thanks a lot smaffulli. I ended up patching my installation and what i did was download both "patches" from github and cd into requirements and do "python update.py /path/to/nova" and then into nova i did "python setup.py install --install-scripts /usr/bin"

That patched my nova and it worked. Anyway the circumstances required anoter clean installation of the environment and i took a version that fixed my bug as you suggested so all good now. Thanks again.

2014-12-29 12:35:37 -0500 asked a question Apply patch to nova

Hello everyone, i have an openstack environment based on IceHouse that uses Ceph as a storage backend for glance,cinder,swift and ephemeral (nova) storage. All these work fine but one thing, the instance creation time is too slow. I have raised a question to some people who pointed me to a patch that i can apply to Nova and it will resolve my issue. The patch is https://github.com/angdraug/nova/tree/rbd-ephemeral-clone-stable-icehouse (https://github.com/angdraug/nova/tree...)

Moreover they told me i must install the latest requirements for icehouse from here https://github.com/openstack/requirements/tree/stable/icehouse (https://github.com/openstack/requirem...)

My issue is that i do not really know how to do the installation properly. I believe i should first run the requirements python update.py /path/to/requirements and then do python setup.py /path/to/nova

Is that right or i am missing something??? (when i tried to do setup.py it told me that it cannot be found) Still i am a bit confused. Anyone who could help it would be greatly appreciated.

Thanks a lot in advance
