1. A method for media library management, comprising: executing a media library management application on a media library management system having a computer processor and a memory coupled to the computer processor; issuing a filesystem mount command which is distinct from a tape volume mount command to an operating system of the computer processor, the filesystem mount command initiating a filesystem mount operation that completes without the operating system providing notification of completion; the media library management application inhibiting commands that are dependent upon completion of the filesystem mount operation until the filesystem mount operation is complete; communicating diagnostic information generated by the operating system for the filesystem mount operation to the media library management application; the media library management application determining from the diagnostic information that the filesystem mount operation is complete; and responsive to determining that the filesystem mount operation is complete, the media library management application issuing one or more of the commands that are dependent upon completion of the filesystem mount operation.
