By default, the packstack installer uses either a volume group named cinder-volumes or a loopback device as back end for the Cinder block storage service. For professional purposes, this is not enough; the usual requirement is to have a redundant storage back end. If you have an existing Red Hat Storage service, you might want to use one of the GlusterFS volumes as back end for the block devices your virtual machines use in the Red Hat Enterprise Linux OpenStack Platform cloud.
Before starting the configuration, you must remove all existing Cinder volumes, or you will run into problems. To figure out if there are any existing volumes with your current Cinder setup issue:
If there are any volumes listed, delete them with:
cinder delete volumename
Now that you have a cleaned-up Cinder setup, you can configure the back end to exclusively use the Red Hat Storage GlusterFS volume(s).
Start off by installing the GlusterFS-fuse package on the Cinder host, available in the Red Hat Storage Native Client repository from Red Hat Network.

To install Red Hat Enterprise Linux OpenStack Platform manually can be an odious task, but packstack can assist in making the installation much easier and consistent. Normally, packstack is run from the controller node, which can either be a physical machine or a virtual machine.
Start by installing the machine with the latest Red Hat Enterprise Linux. Subscribe to the Red Hat OpenStack channel, as well as any other channels desired.
Next, install the openstack-packstack package using yum: ~]$ sudo yum install openstack-packstack
As root, use packstack to generate an answer file: ~]# packstack –gen-answer-file ~/answers.txt Continue reading →
During this year’s Red Hat Partner Conference EMEA in Madrid, Spain, Red Hat Training gave an update on its new training and certification roadmap. The event covered new delivery methods and courses, including a three day exam marathon during which a total of 70 partner employees had a chance to take a free-of-charge certification exam. In addition, a training partner round table was held to discuss new opportunities for Red Hat Training and our partners. As is tradition, we also held an awards ceremony, recognizing those that have made the biggest impact over the course of the last year in training and certifications.
It is with great pleasure that I reveal the awards given that night:
