Hi Guys, Need some help, just installed a new high availability cluster using ubuntu 14.04 and openstack ice house. Configuration example if the static compute host generation is used: Define the cmp<NUM> control address and hostname in the <cluster>/openstack/init.yml file: Apply the reclass.storage state on the Salt Master node to generate node definitions: Verify that the target nodes have connectivity with the Salt Master node: Then I reached this stage and ran the following command on the controller node. shut down) the compute node. Mirantis Documentation: Reprovision a compute node openstack - Adding new compute nodes to a devstack ... However, if you want to deploy a higher number of nodes, Red Hat has successfully tested up to 100 nodes simultaneously. A compute node (nova-compute) A storage area network (SAN) used by OpenStack Block Storage (cinder-volumes) The worst disaster for a cloud is power loss, which applies to all three components. A controller node may also include the Oracle OpenStack for Oracle Linux toolkit, which is used to perform the deployment of OpenStack services to other nodes. It's unnecessarry to set Bridge networking on the section [2] of the link. I am beginner in openStack. Chapter 5. Migrating virtual machine instances between ... Chapter 1. Deploying Distributed Compute Nodes to Edge ... To verify that the new server has been placed correctly, run the following command and check for OS-EXT-SRV-ATTR:hypervisor_hostname in the output: nova show <server-name>. What is openStack Compute Node? - Super User There is no globally-unique identifier for a compute node within the OpenStack deployment, and we need a globally-unique identifier for the resource provider. I've just created two Fedora 20 VM's. In the first one I ran the openStack Controller, which started the web interface of openStack. I don't know exactly what is a openStack compute node. Wanted to remove a compute node from the openstack setup. A compute node runs the bare minimum of services to manage virtual machine instances.
