Thanks
... about that quorum role ... Minio does not support quorum typde nodes (or arbiters in MongoDB nomenclature).
I just named it like that 'logically' as this 3rd site - IN MY SCENARIO - where most nodes are in 1st and 2nd datacenter can be 'lost' without impact on the cluster work and if I lost only site A (1st) then this 'quorum' node serves that role to have more then half of the nodes, server quorum node.
The 'quorum' node in my setup still has data on it, but only 2/16 of that data, the 'data' nodes have 7/16 of data, which will be 14/16 for 'data' nodes and 2/16 for 'quorum' logical role node.
Hope that helps, sorry for misunderstanding.
