Hi Folks,
It is pretty well know that disk performance start to suffer when the partition begins to fill up.
So I am wondering if you would see the same effect with a full volume (traditional or flexible) in a relatively empty aggregate, or a full qtree in a relatively empty volume?
Any thoughts on the matter would be appreciated.
As I understand it, WAFL write performance depends on a reasonable supply of free blocks. All volumes in an aggregate share the same pool of free blocks, so that implies that if the aggregate has plenty of free blocks, then WAFL write performance should be efficient for the entire aggregate, regardless of how full the volumes are.
