kolla-ansible redeploy single service on single node (gnocchi_metricd failure)
I've got a multinode cloud recently deployed with queens, with each compute/ctrl/neutron/storage serviced by two separate nodes. I've had to use the git-repo for kolla-ansible (stable/queens), since it always fails on db-issues otherwise)
It looks to be working now, but for some reason the gnocchi_metricd container is repetitively failing on ONE controller node.

I've been trying to figure out what the difference is, in configuration of the two containers on CTRL-1 and CTRL-2, but I cant find anything except IP-addressing.
So...I would like to do something like
kolla-ansible -i multinode ReDeploy --only gnocchi_metricd
How can I do that?
Somewhat related to that, I've also been looking for how I would go about adding a new Openstack component, to my existing deployment. So if I deploy without, say for instance tacker, and then want to add tacker in afterwards, how? The references at https://docs.openstack.org/kolla-ansi... arent super clear since they say things like, run: "kolla-ansible deploy", but without any references to "-i multinode", and no description of what happens with all the already existing services?
Will a normal "kolla-ansible -i multinode deploy" ignore existing containers?
Hello,
Did you find the answer to your question? i am also looking for the same information.
