I am moving some nodes to a new storagepool, from a non-colocated one to
a colocated one.  I updated the copygroup definition to point to the new
storagepool and new backups are going there.  I used move nodedata to
move the old data from its primary tape pool to the new one.  My regular
backup stgpool moved the data from the new promary storage pool to the
new offsite storage pool.  How do I now get rid of the data on the old
offsite storagepool.  I thought it would expire when the offsite copy
was made to the new storagepool but that does not seem to be the case.
