        Right, that's what I gleaned from the admin guide.

        Right again. My primary storage pool has two drives, in fact, I see
reclaim going on for that storage pool.

        I left my copy storage pool reclaim threshold value at 40 over the
weekend. No reclaim took place for my copy pool, and I still have
volumes with > 40% reclaimable space.

        The Admin guide says reclamation threshold is "The percentage of
reclaimable space that a sequential access media volume must have before
the server can reclaim the volume." I have the reclamation threshold
parameter for the copy pool set to 40, so I should expect volumes with >
40% recaimable space to be reclaimed, right?

        Is there anything else that could prevent reclaim from occurring? As
far as I can tell, I've set it up properly.

        Big thank you to everyone who responded!

Jon
