Verify Ceph cluster state¶
To verify the state of a Ceph cluster, Ceph Controller provides special
sections in KaaSCephCluster.status
on a management cluster. The
resource contains information about the state of the Ceph cluster components,
their health, and potentially problematic components.
To verify the Ceph cluster state from a management cluster:
Obtain
kubeconfig
of a management cluster and provide it as an environment variable:export KUBECONFIG=<pathToMgmtKubeconfig>
Obtain the
KaaSCephCluster
resource in YAML format:kubectl -n <projectName> get kaascephcluster -o yaml
Substitute
<projectName>
with the project name of the managed or management cluster where the required Ceph cluster is placed.Verify the state of the required component using the KaaSCephCluster.status description.
To verify the Ceph cluster from a managed cluster:

of a managed cluster and provide it as an environment variable:export KUBECONFIG=<pathToManagedKubeconfig>
Obtain the
MiraCeph
resource in YAML format:kubectl -n ceph-lcm-mirantis get miraceph -o yaml
Information from
MiraCeph.status
is passed to themiraCephInfo
section of theKaaSCephCluster
CR. For details, see KaaSCephCluster.status miraCephInfo specification.Obtain the
MiraCephLog
resource in YAML format:kubectl -n ceph-lcm-mirantis get miracephlog -o yaml
Information from
MiraCephLog
is passed to thefullClusterInfo
andshortClusterInfo
sections of theKaaSCephCluster
CR. For details, see KaaSCephCluster.status shortClusterInfo specification and KaaSCephCluster.status fullClusterInfo specification.
