Two quick (and probably obvious) points: - You can do multiple simultaneous reclamations if you have multiple storage pools. Long on tape drives? Create another domain (& storage pool(s)) and split your nodes between them.
- MOVE DATA (tape to tape, or tape back to disk) allows multiple simultaneous processes on one storage pool and each is often faster than the corresponding reclamation. The down-side to MOVE DATA is that aggregates are not reconstructed, so your newly filled tape will immediately have reclaimable space. Perhaps a statistician could tell us the expected wasted space remaining after a MOVE DATA. Maybe with too many caveats to be useful, ... but when I switched from exclusively performing MOVE DATAs to exclusively performing reclamation, I "gained" almost 20% empty volumes. cheers, wayne Wayne T.
