* The repo id was determined wrong when the delete picked up on an in progress snapshot * NOTE: This solution is still a best-effort fix and there's a slight chance of running into concurrency issues here when multiple create and delete requests for the same snapshot name are happening concurrently, but these require a sequence of multiple cluster state updates between the changed method reading the genId and submitting its cluster state update task * Added test reproduced the issue reliably in about 50% of runs * Closes #37581

There was a problem hiding this comment.
LGTM. The new snapshots test infrastructure is already paying off.
