Description of problem: The current GSS best practices guide recommends bucket index to be on separate nvm drive compared to journal, During the DFG workload testing, John noticed too much traffic is on the filestore journals and there is not really advantageous to have bucket index on different nvme, the recommendation from the experiment is to split on same nvme probably using lvm, we need to update our best practices guide based on this testing.
So what John is recommending here is with LVM option that is equally split between journal and bucket index on same nvme.

One minor nit but looks good.
