"rbd"?

Shouldn't it be enough just to "disable" those services/backends?

I guess I have to, because just commenting that out didn't help, they still
show as enabled and running.

But even after disabling them, they're still show as "status=disabled,state=up"
with a "cinder service-list".. ?

Ok, good! I thought I missed something fundamental.

That's the Control node..

10-15 seconds perhaps. At least less than (half?) a minute..

It is not obvious from that that that (!! :) should only be done on the
Controller! It just say "do this on the controller". It does not make it
clear that you shouldn't do something on the compute as well.

Neither of which distinguish the different parts - what if I
have/want a separate compute and control node? It does not
make things obvious!


And that's why I have a problem with HOWTOs! They _assume_ to much.
And a _BAD_ HOWTO (which all of them on Openstack are!) doesn't even
attempt to explain the different options you have, so if you deviate
even the very slightest, you're f**ked!

There's a _HUMONGOS_ difference between a "HOWTO" and "Documentation"!

I was doing that ON the Control. Worked just fine.

And The Control and Compute is on the same switch.
