My control nodes don't but that shouldn't matter from my understanding.

( Control01,2,3 are an HA cluster sitting behind haproxy/keepalivd running
all the communication and schedulers  -all that is working well.)

 

 

I get this error in my cinder-volume.log on the control nodes(since they run
schedulers) There is nothing else to go off of other then "ERROR" on the
volume status.

 

2013-12-04 12:55:32  WARNING [cinder.scheduler.host_manager] service is down
or disabled.

In case you can't see excel  below.

192.168.220.40 Is the proxy being distributed into the three control nodes.

Any ideas on where to look more into the issue or something with my config?

So this happens in a couple of situations, the most common is when there's
not enough space/capacity being reported by the configured backend driver to
allocate the amount of space you're requesting.  Try a "sudo vgs" and verify
that you have enough capacity on your backing store (nova-volumes) to deploy
a 10G volume.
