using packstack to add additional compute node

I just use the packstack to add two compute nodes in my existing multi-nodes openstack cluster, but something is not right. i can type some commands like "nova list" in new added nodes, but these two nodes are not in the nova hypervisor list. Am I using the packstack in wrong way? I used the answer file which was used to install my existing openstack cluster, only two places were modified: EXCLUDE_SERVERS=[the list of nodes in existing openstack cluter] CONFIG_COMPUTE_HOSTS=[list of existing compute nodes + two new added compute nodes]

anyone else happen to meet this problem before?

If you look at the nova-compute.log on your new compute hosts, does it appear to be successfully connecting to your AMQP server?

Hi larsks,

yes, it is. The new compute node can not reach the AMQP service, so I restart the corresponding service in the controller, it works now. thanks very much.

In your existing answer file change only the CONFIG_COMPUTE_HOSTS. CONFIG_COMPUTE_HOSTS=compute1-IP,compute2-IP


re-run the packstack installation with the following command and it will generate new answer file. packstack --install-hosts=<compute1-ip>,<compute2-ip>

you can find your compute nodes in nova availability jone list.
