1. Proposed title of this feature request High Availability Quantum Network Scaling 2. Who is the customer behind the request? Account: name (acct #) 1403700 TAM customer: no/yes yes SRM customer: no/yes yes Strategic: no/yes yes 3. What is the nature and description of the request? As per redhat documentation Quantum, routes all traffic through a single node, which is resulting a single point of failure. Currently this is the only supported method of quantum right now. 4. Why does the customer need this? (List the business requirements here) Quantum presents a single point of failure for the entire RHOS environment. 5. How would the customer like to achieve this? (List the functional requirements here) Is it possible to setup Quantum on top of a cluster ? 6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented. 7. Is there already an existing RFE upstream or in Red Hat Bugzilla? NO 8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)? NO 9. Is the sales team involved in this request and do they have any additional input? No 10. List any affected packages or components. openstack-quantum-2012.2.3-5.el6ost.noarch
gkotton/mnewby/rkukura: This should be addressed in RHOS 3.0 partially after we include netns support, correct? Can one of you outline what the current state of HA for RHOS 3.0/Quantum will be in this bug?
Hi, I am not sure that this will be something that will be ready for RHOS 3.0. There are 2 parts: 1. Scale - RHOS 3.0 has support for this for the DHCP and the L3 agents - DHCP agents can be assigned networks - Routers can be assigned to l3 agents 2. HA - The DHCP agents have HA. Tis requires manual configuration by the user. An upstream patch has been added to automate this (https://review.openstack.org/#/c/27907/). This is still in review. An additional patch needs to be added that will automatically select another DHCP agent if an existing agent goes down. This will be done in te near future. This is certainly something that can be added to RHOS 3.0. - There is no HA fo the l3 agents. There is work being done upstream on this at the moment. I hope that it may be in by the middle or end of the Havana cycle. We need to follow this and see how it can be addressed in RHOS. (https://blueprints.launchpad.net/quantum/+spec/quantum-multihost) Thanks Gary
Based on the explanation in Comment #3, it seems that OpenStack Networking HA really needs to be reassessed following the Havana release cycle upstream, so this bug needs to be moved to RHOS 4.0 to be reevaluated following the Havana release cycle.
