adding disk to aggregate + dedup + reallocate plan

8.1.3 7 mode

Currently aggregate is setup like this:

2 X 16 rg

RAID-DP

both rg are full of disks

I have 6 spare disks I want to add.

All volumes on this aggregate are heaveliy deduped.

Whats the best practice to approach this? Add a new rg? increase rg size on both rg? how to do reallocate? I read its a big no no to reallocate when dedupe is on.

So what's the best approache?

Thanks
