Re: [Openstack] controller redundancy

Ahh, OK, I think I know what you're talking about. You don't really need that network you're referencing since you'll be providing the gateway services (HA as well if desired) on a device(s) completely outside of OpenStack. You can mark a new network as 'External' and/or 'Shared' via check

Re: [Openstack] controller redundancy

Maybe I'm misunderstanding what you're getting at. I can create both public and private networks within OS9.2 using just VLANs. I can also create networks on VLANs that are outside of the tenant VLAN range I specified in Fuel prior to deployment under the Neutron L2 section. On 04/13/2017

Re: [Openstack] controller redundancy

I'm running Mirantis OS 9.2 and using VLANs so you should be able to as well without using OS11. It should provide you the option to use VLAN segmentation for networking while running the cloud environment creation wizard. Once you create the cloud environment, you can't change this option,

Re: [Openstack] controller redundancy

This is only if you're using the controllers to serve as a gateway to the Internet or to direct incoming traffic to the VMs. If you use a VLAN only network configuration to offload the gateway to an external device (router or l3 switch) or you use Neutron in DVR mode, this shouldn't be an

Re: [Openstack] controller redundancy

Fyi, the idea of controllers are a bit of a misnomer. You should have redundant services; they don't necessarily need to be on the same box. Since your asking as a new user. Have fun! //adam On Apr 12, 2017 5:27 PM, "Konstantin Raskoshnyi" wrote: > Yes, machines are still

Another FYI, OpenStack services don't have to be running to access a virtual machine. Period. Amy other condition that prevents this is a serious design flaw. //adam On Apr 13, 2017 5:31 AM, wrote: > Fyi, the idea of controllers are a bit of a misnomer. You should have > redundant services;

Re: [Openstack] controller redundancy

hi, depends on what you mean by inaccessible, your VM is probably still up and running on the compute node. but you won't be able to access them remotely as your controller node ( which is hosting neutron ) is down. regards, nhadie On Apr 12, 2017 11:31, "Konstantin Raskoshnyi"

Re: [Openstack] controller redundancy

Yes, machines are still running, but since neutron is down none of them can be accessible. On Wed, Apr 12, 2017 at 5:10 PM ron ramos wrote: > hi, > > depends on what you mean by inaccessible, your VM is probably still up and > running on the compute node. but you won't be able

Re: [Openstack] controller redundancy

Actually I found that a need a minimum 3 controllers to work fine. Not sure about working without controllers though. Thanks On Wed, Apr 12, 2017 at 4:20 AM Yura Poltoratskiy wrote: > Hi, > > I do not familiar with mirantis os 9, but in general there is an > architecture

Re: [Openstack] controller redundancy

Hi, I do not familiar with mirantis os 9, but in general there is an architecture when vm can be still accessible even without controller. Also, there is a guide for HA deployment, here are for controllers in particular - https://docs.openstack.org/ha-guide/controller-ha.html On

[Openstack] controller redundancy

Hi guys, I'm new to openstack. Installed mirantis os 9, If one of controllers goes down - vm machines are not accesible, I though openstack supposed to work even if one controller is alive Any thoughts? ___ Mailing list:
