Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!
Now, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.
Verify rook-discover¶
Warning
This procedure is valid for MOSK clusters that use the deprecated KaaSCephCluster custom resource (CR) instead of the
MiraCeph CR that is available since MOSK 25.2 as a new Ceph configuration
entrypoint. For the equivalent procedure with the MiraCeph CR, refer to the
following section:
To ensure that rook-discover is running properly, verify if the
local-device configmap has been created for each Ceph node specified
in the cluster configuration:
Obtain the list of local devices:
kubectl get configmap -n rook-ceph | grep local-device
Example of a system response:
local-device-01 1 30m local-device-02 1 29m local-device-03 1 30m
Verify that each device from the list contains information about available devices for the Ceph node deployment:
kubectl describe configmap local-device-01 -n rook-ceph
Example of a positive system response:
