What is a use case of setting a reservation on the base pool object? Say I have a pool of 3 100GB drives dynamic striped (pool size of 300GB), and I set the reservation to 200GB. I don''t see any commands that let me ever reduce a pool''s size, so how is the 200GB reservation used? Related question: is there a plan in the future to allow me to replace the 3 100GB drives with 2 200GB drives? --Naveen This message posted from opensolaris.org

Pool itself is a filesystem so it''s the same reservation as for
filesystems.

You can do it right now - just use zpool replace. Once you''ve replaced
all three disks a pool will grow automatically.
