By default both cinder and nova-api are listening on the same port 8776
(this should be a bug I think), you can try to change the default value in
the cinder.conf like: osapi_volume_listen_port = 8777 if you are running
the cinder and nova-api on the same machine.

Hello,

Can someone please help me with a nova-api issue.  After install all the
nova services, all seem to be running fine, except for nova-api.  I even
reboot my controller node, no luck.  After reboot all services are running,
except nova-api.  When I manually start nova-api, nova-api crashes with the
following error "error: [Errno 98] Address already in use".  I installed
nova-volume earlier during the install process, but later on installed
cinder, and made the necessary modifications (as far as I can tell) to
nova-api.conf to use cinder for block storage.  Should I uninstall
nova-volume?

                  I am running cinder-api.   The following two lines are
                  present in nova.conf.

                  volume_api_class=nova.volume.cinder.API
                  enabled_apis=ec2,osapi_compute,metadata

                  Do I need to re-sync the db, or add any additional lines
                  to nova.conf?

            No that is it. Are you sure a) you don't have another nova-api
            or nova-metadata or nova-api-os-compute process running? and b)
            that your nova.conf is being read properly?

            Vish

      As far as I can tell, no other nova-api, nova-metadata,
      nova-api-os-compute is running.   If there another way to confirm
      besides running "ps aux".  And how can I tell if nova.conf is being
      read properly?

      Can you help me understand the following error message in the file:

      2012-11-08 23:31:27 CRITICAL nova [-] [Errno 98] Address already in
      use

      By address, are we talking about tcp port number? If so, what is the
      port number?

      Thank you,
      Ahmed.
