As per Tr-4571 best practice for a FAS based flexgroup is 2 aggregates per node.
What would be the conequences of adding a 3rd aggregate per node.
Environment
6 node FAS8200 cluster 3x DS460C shelves per pair loaded with 10TB drives
ONTAP 9.7P5
2 data aggregates per node ~288TB per aggr
Aggregates are 42x 10TB drives 12 drive RAID-TEC raid groups.
4 member volumes per aggr, ~68TB
so far so comforming to the Tr
Single flexgroup spans the cluster and is approaching 95% full
Customer has additional shelves available and would like to expand the flexgroup.
Adding an aggregate breaks the 2 per node best practice rule
Adding a raid group breaks the 400TB aggr size limit
So without adding nodes what would the implications be of adding a 3rd aggregate per node. I'm loath to break best practice
