gke-ai-troubleshooting-tpu-partition-overlap

Diagnose and resolve GKE TPU slice creation failures (SliceCreationFailed) caused by partition overlap conflicts where requested TPU partitions or their nodes are already used by another slice or JobSet. Use when diagnosing GKE TPU slice creation failures with SliceCreationFailed partition or node conflicts. Don't use for general slice lifecycle states or slice provisioning failures without node overlap (use gke-ai-troubleshooting-tpu-dynamic-slices-monitoring), quota exhaustion, or unresponsive TPU nodes.

# Troubleshoot TPU slice creation failures caused by partition overlap

A dynamic slice fails to form with the status reason `SliceCreationFailed` when,
among other documented causes, any of its nodes are already used by another
slice. This skill confirms the failure, rules out the other documented causes,
finds the slice that uses the same nodes, and routes the fix through GKE.
