Verify rook-discover¶
Warning
This procedure is valid for MOSK clusters that use the MiraCeph custom
resource (CR), which is available since MOSK 25.2 to replace the unsupported
KaaSCephCluster resource. And MiraCeph will be automatically migrated
to CephDeployment in MOSK 26.1. For details, see Deprecation Notes:
KaaSCephCluster API on management clusters.
For the equivalent procedure with the unsupported KaaSCephCluster 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:
