Chapter 6. Post-deployment configuration
After the overcloud deployment finishes, complete the following steps to validate the functionality.
Procedure
Create a test instance in the availability zones. In this example, the new instance runs on the distributed compute node (DCN). The specific AZ is targeted using the
--availability-zone
parameter:$ openstack server create --flavor m1.tiny --image cirros --network private --security-group basic dcn-instance --availability-zone dcn0
Create a volume on the first availability zone. This volume uses the cinder active/active service running on the
dcn0
nodes.$ openstack volume create --size 1 --availability-zone dcn0 myvol
NoteThis step depends on the cinder availability zone configuration, which is defined by
CinderStorageAvailabilityZone
. For more information, see Deploying availability zones in the Storage Guide.
You now have two separate HCI stacks, with a Ceph cluster deployed by each one. For more information on HCI, see Hyperconverged Infrastructure Guide.
6.1. Checking container health
Verify that the container is functioning correctly.
Procedure
- Log in to the node that is running the Ceph MON service by using SSH.
Run the following command to view container health:
$ podman exec ceph-mon-$HOSTNAME ceph -s --cluster CLUSTERNAME
Replace
CLUSTERNAME
with the name of the cluster, for example,dcn0
. The default value isceph
.-
Confirm that the health status of the cluster is
HEALTH_OK
and that all of the OSDs areup
.
