The metadata server does not have access to user volumes and therefore relies on clients to verify the actual size of user volumes. In this case, no clients with access to the specified volume had been active, so the metadata server does not know the actual volume size.
Issue the lsvol command to determine the name of the volume and then issue the reportclients command to list all clients with access to the volume. It is recommended that you make at least one of these clients active on the master metadata server before checking metadata.
