Excellent!

Now I wonder if one more "option" would be useful?  Would it be possible to
limit the number of  cartridges recycled?

Something like;

update stgpool dltpool reclaim=90 reclaim_at_most=3

So that a reclaim will only do the emptiest 3 cartridges?

Do people think this would be useful?

I'd use this to limit the impact reclamations would have on other sessions.
I could lower the reclaim limit in the morning, unitl the reclaim kicks off
and then raise it again.  It would then process just the 3 emptiest
cartridges and then end so it would be more predictable as to how long it
would take.

We have made a recent enhancement to the reclamation volume selection
algorithm.  Reclamation will now select the volumes in a predictable order,
emptiest to fullest.   This way it will quickly reclaim those volumes first
that
do not contain much data.  It may of course need to mount other volumes
if files span between the volumes.

This enhancement (or fix) is coming soon to to PTF near you!
