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:

1. 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
   

2. 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:

   Name:         local-device-01
   Namespace:    rook-ceph
   Labels:       app=rook-discover
                 rook.io/node=01
