    I am consolidating data in the primary pools by 'move nodedata ' .
    The data is for nodes that are not active/decommissioned.
    After consolidation the data is moved to a new pool.
    i.e old-backup_pool --> new_nactive_pool.
    The copy of the data resided on the old-copy pool.
    I ran move nodedata node_name fromstgpool=old_copy-pool tostgpool_old_copy-pool
    with intention to consolidate the copy volumes.
    The job ran with success almost instantly,
    I think the data on the primary pool is already consolidated and the copies are pointing to new pool.
    However the volumes on the copypool still shown in the q nodedata command.
    Nothing got consolidated yet.
    My question : Do I need to run backup new_inactive_pool to old_copy_pool to force the consolidation of the copy volumes?
    Does anyone had a similar issue?
    Thank you,
    Al

    The copypool didn't change by your primary pool consolidation. The objects that are in the new pool that were already in the copy pool are still in the copy pool and still referencing the same objects. So if you were to lose the new primary pool today, you can recover it from the existing copypool.

    You can use move nodedata to do a similar thing on the copy pool, with the exception that you can't move the data to a different copy pool.

    Thank you for the reply.
    I did try to do exactly this : move nodedata nodeX fromstgpool=copyX tostgpool=copyX and it did run for a second with cc=0.
    The q nodedata still shows the same allocation for multiple copy tapes.
    One thing I noticed was that the copy pool has a 10 day volume reuse.
    Could this be the cause for the delay?
    Thank you,
    Al

    I finally have an answer to the issue.
    Very simple , - there is an undocumented ( at least I could not find it) restriction on move nodedata for copy pools.
    In order to consolidate it all the copy pool volumes must be on site. In my case the copypool was an offsite pool.
    Quite interesting that the message completion is "successful" , while it should be changed to something meaningful like "process completed , data was not moved"
    and my mental block of assuming that the command works aka reclamation is gone now.
