Hi, i have seen a lot of posts regarding the addition of disks to an aggregate but wants to run something past the group. I want to change the disk layout as per the attached. (all disks are currently in rg0) I have 10 spares available on the node1 and 22 available on node2. I was thinking of allocating 4 drives from the node2's disks to node1 and add these disks as 2 spare and 12 data disks as RG1 for the current aggregate. That will leave node2 with 2 spare and 16 data disks which should work out round about 48Tb usable on node2. I also saw that no disk reallocation is needed any longer. These systems are running ONTAP 9.15.1P6
#Adding disks to an AFF Aggregate

I’m a huge fan of symmetry. Those “spares” you see on an aff are partitions. Each node has a data partition on every disk. Just keep it simple. Have a data aggregate in each node. The same size. The same number of disks

Nope - ADP was not used on this systems.

Why not? That’s simply wasting expensive SSD space
Is there data on the system? If not I’d start over and reinit started with adp
Plus you don’t indicate the platform. Depending on platform the disk ownership may be incorrect like things were manually assigned. Depends on platform but most aff platforms will assign ask disks on left half to one node and the right half to another.
Still stands: symmetry
If you plan to use both nodes (as you should) then you should split the aggregates evenly
And I’m also only seeing two disks for the root aggregate. Why? Should be a minimum of three. Better yet adp to get lots of space.
