Verify rook-discover¶
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:
