From 4288973a9efc88c5555f56d86b4c7a3222091746 Mon Sep 17 00:00:00 2001 From: Jason Hernandez <7144515+jasonhernandez@users.noreply.github.com> Date: Wed, 9 Sep 2026 16:22:10 -0700 Subject: [PATCH] misc/scratch: move prod-like-arm to Graviton4 The `prod-like-arm` scratch config still launched an `r6g.4xlarge`. Production's ARM node pools have moved on: the pools that carry weight today are `arm-swap` and `arm-jumbo-swap`, both on the `r8gd` family. Staying on Graviton2 means the box under test no longer matches the microarchitecture production runs on. Move the family to `r8g` and keep the size at `4xlarge`, so the CPU generation tracks production while the footprint and cost of the box are unchanged. Production uses the `d` variant for its local NVMe, which backs swap and the scratch filesystem. This config stays on plain `r8g`: nothing in `misc/scratch/provision.bash` mounts an instance store, so the extra disk would go unused.
