I will be able to tell next week.
We are currently in a pilot with two hosts and have run into the issue (right now our main pool will always lean on one of the two hosts). So I am manually balancing by hiding and showing whichever SSD/Host I want to fill up)
We did not have the issue when we started out (dec) and now it is consistent (I suspect that creating a new pool could reset the issue but our current pool update strategy gradually recomposes the pool everyweek so we never actually delete it).
We are upgrade everything from 5.1 to 5.2 friday night.
Will report back.
