Backup files are sometimes segmented and spread across two or more
storage pool volumes. If a volume below the reclamation threshold
contains one segment of such a file the volumes containing the
other seqments will also be required as input volumes for reclamation.
I don't know of any elegant way to identify the other volumes in such
cases. The ugly way I am aware of starts by running a pair of "query
content" commands with "count=1" and "count=-1" against the below
threshold volume to find out whether that volume starts or ends with
a segmented file. If it does, one can run similar commands against
the other volumes in the same storage pool and look for matching
file names.
