Verify Ceph cluster state¶
To verify the state of a Ceph cluster, Ceph Controller provides special
KaaSCephCluster.status. The resource contains information about
the state of the Ceph cluster components, their health, and potentially
To verify the Ceph cluster state from a managed cluster:
kubeconfigof a managed cluster and provide it as an environment variable:
MiraCephresource in YAML format:
kubectl -n ceph-lcm-mirantis get miraceph -o yaml
MiraCeph.statusis passed to the
miraCephInfosection of the
KaaSCephClusterCR. For details, see KaaSCephCluster.status miraCephInfo specification.
MiraCephLogresource in YAML format:
kubectl -n ceph-lcm-mirantis get miracephlog -o yaml
MiraCephLogis passed to the
shortClusterInfosections of the
KaaSCephClusterCR. For details, see KaaSCephCluster.status shortClusterInfo specification and KaaSCephCluster.status fullClusterInfo specification.
To verify the Ceph cluster state from a management cluster:
Ceph changes in Container Cloud 2.20
Since Container Cloud 2.20.0, the Ceph cluster does not deploy on management and regional clusters to reduce resource consumption.
Ceph cluster is automatically removed from existing management and regional clusters during the Container Cloud update to 2.20.0.
Managed clusters continue using Ceph as a distributed storage system.
KaaSCephClusterresource in the YAML format:
kubectl -n <projectName> get kaascephcluster -o yaml
<projectName>with the project name of the managed or management cluster to which the required Ceph cluster belongs.
Verify the state of the required component using KaaSCephCluster.status description.
