[OpenIndiana-discuss] ashift 13?

[Jason Matthews]

Well, the inflation is definitely caused by using 8k sectors. Sending 
that same snapshot back to a pool configured for 512b reduces its 
utilization to 200gb

That is frustrating. I just launched 64 slaves with pools set for 8k 
secords. It seems to cost twice as much storage to operate with native 
write sizes. That just doesnt make sense to me (yet).


I wonder what 4k write sizes look like. Let's find out.
