Troubleshoot GKE TPU slice creation blocked by an unstable MIG This skill helps diagnose GKE TPU Dynamic Slice creation failures and JobSet scheduling delays when the Compute Engine managed instance groups (MIGs) that back the TPU node pool aren't stable ( ). A status reason means that slice creation failed because prerequisites weren't met (for example, required Compute Engine resources are missing) or preflight checks failed (see Use dynamic slicing with a custom scheduler). A MIG that is still creating, updating, or repairing instances is one cause to check. This skill checks the slice sta…
