Ceph » rbd

"rbd-wnbd map" commands are delegated to the centralized ceph-rbd Windows service, which in turn will create the actual image mapping. This allows the daemons to continue running even after the current session ends.

rbd-wnbd communicates with the service through a named pipe. If the operation fails, we're only getting an error code.

We should print the according error message based on the error code, suggesting the user to check the logs or use foreground mode ("-f") for additional information.

We could also capture the entire subprocess console output and print it in case of errors. This can be quite verbose, so we'll keep it simple for now.
