You do have to turn on the DIRF bit and force an allocation to the volume to get CVAF(?) to tidy up the vtoc space information on a volume with an indexed vtoc. >Regards, >John > I've never had to do that for a volume only shared between MVS systems. But to answer your question, the space according to the VTOC is correct. It's SMS's knowledge of what is free on the volume that is not correct since it only updates the COMMDS when a data set is allocated or deleted on the volume from that SMSplex. See the post I referenced before.
