Upgrade DOT requires free aggregate?

Support told me to "free up" the aggregate before they can upgrade the DOT from 8.1 to 8.1.2FP2, because the aggregate is 95% used.

But pls correct me if I'm wrong.

In my opinion, the important thing is the space available in a volume, not aggregate, isn't it?

Aggregate means only the physical disk. And volume is the one used by data and also DOT.

So:

True 95% of aggr0 is assigned to vol0. But any future data including DOT upgrade will be written on the vol0, not the aggregate directly.

So, I believe I don't have to add disk to aggr0? vol0 still has lots of space.

Re: Upgrade DOT requires free aggregate?

Yep, vol0 is by default thick provisioned, so there should be place on your vol0.

Thank you Aleksandar

Re: Upgrade DOT requires free aggregate?

The support engineer replied to me below. 

But I don't get it. I think the doc means "amount of space in use by each aggregate" = "amount of space in use by each volume", doesn't it?

Re: Upgrade DOT requires free aggregate?

Hi Fajar,

Your support engineer response is correct "amount of space in use by each aggregate".

The upgrade need free space in AGGR to move data around.

Good luck
