@AlexDawson ,
In our case, we added the new 24x890GB SSD for increasing the required root volume size, but didn't partition them as you suggested we should.
As it is now, I am interested in two options that you pointed out, and would like you to weigh in which one I should go for.
1. With total of 18x890GB, creating a new aggr on a node would cause two nodes in HA out of balance, personally, I prabably would not prefer.
2. Adding 9x890GB to each node into the existing aggr as a new rg, AND deducting two disk as parities, that would probably add 6TB more in each aggr, assuming the size mismatching is alright, is it worth doing it?
I am going to send you 2 serial numbers for these two new heads. Due to issues here with sending out on-demand Autosupport, you might not be able to see the updates, but there is a manually trigged one there.
Thanks a lot for your time.
