Chapter 8. Post-deployment


The following subsections describe several post-deployment operations for managing the Ceph cluster.

8.1. Accessing the overcloud

The director generates a script to configure and help authenticate interactions with your overcloud from the director host. The director saves this file (overcloudrc) in your stack user’s home directory. Run the following command to use this file:

$ source ~/overcloudrc
Copy to Clipboard Toggle word wrap

This loads the necessary environment variables to interact with your overcloud from the director host’s CLI. To return to interacting with the director’s host, run the following command:

$ source ~/stackrc
Copy to Clipboard Toggle word wrap

8.2. Monitoring Ceph Storage nodes

After you create the overcloud, check the status of the Ceph Storage Cluster to ensure that it works correctly.

Procedure

  1. Log in to a Controller node as the heat-admin user:

    $ nova list
    $ ssh heat-admin@192.168.0.25
    Copy to Clipboard Toggle word wrap
  2. Check the health of the cluster:

    $ sudo podman exec ceph-mon-$HOSTNAME ceph health
    Copy to Clipboard Toggle word wrap

    If the cluster has no issues, the command reports back HEALTH_OK. This means the cluster is safe to use.

  3. Log in to an overcloud node that runs the Ceph monitor service and check the status of all OSDs in the cluster:

    $ sudo podman exec ceph-mon-$HOSTNAME ceph osd tree
    Copy to Clipboard Toggle word wrap
  4. Check the status of the Ceph Monitor quorum:

    $ sudo ceph quorum_status
    Copy to Clipboard Toggle word wrap

    This shows the monitors participating in the quorum and which one is the leader.

  5. Verify that all Ceph OSDs are running:

    $ ceph osd stat
    Copy to Clipboard Toggle word wrap
