Verify Ceph cluster state prior to Container Cloud 2.11.0¶
This document reflects Ceph cluster state verification for Container Cloud clusters versions earlier than 2.11.0. For Container Cloud clusters 2.11.0 and later, refer to Verify Ceph cluster state.
To verify the state of a Ceph cluster, Ceph controller provides a Kubernetes
API that includes a custom
MiraCephLog resource. The resource contains
information about the state of different components of your Ceph cluster.
To verify the Ceph cluster state:
kubeconfigof the management or managed cluster and provide it as an environment variable:
kubectl get miracephlog rook-ceph -n ceph-lcm-mirantis -o yaml
Verify the state of the required component using the
