Is there another openstack service that allows this so we can make the API consistent between the two when this change is made? On Thu, Jan 8, 2015 at 3:09 PM, Carl Baldwin c...@ecbaldwin.net wrote: I added a link to @Jack's post to the ML to the bug report [1]. I am willing to support

+1 on need for this feature The way I've thought about this is we need a mode that stops the *automatic* scheduling of routers/dhcp-servers to specific hosts/agents, while allowing manual assignment of routers/dhcp-servers to those hosts/agents, and where any existing routers/dhcp-servers on

Totally correct, that’s what I was meaning with “will remain active” but “unmanaged”. Yes, it would be good to have something to tell the schedulers to ban a host. Miguel Ángel Ajo On Thursday, 8 de January de 2015 at 00:52, Kevin Benton wrote: The problem is that if you just stop the

You can stop the neutron-dhcp-agent or neutron-l3-agent, the agents should go not-active after reporting timeout. The actual network services (routers, dhcp, etc) will stay active into the node, but unmanaged. In some cases, if you have automatic rescheduling of the resources configured, those

The problem is that if you just stop the service, it not only removes it from scheduling, but it stops it from receiving updates to floating IP changes, interface changes, etc. I think it would be nice to have a way to explicitly stop it from being scheduled new routers, but still act as a

Miguel, Kevin, Thank you for your comments. The motivation of this (from our customer) is about design of network-node reduction procedure. They prefer stop scheduling for agents on the node at first then individual services are moved by *-remove and *-add gradually rather than stopping all
