From 1b8f2364e53c3098c1d188263cef94711b79bcc5 Mon Sep 17 00:00:00 2001 From: xzxiong Date: Sun, 31 May 2026 23:44:31 +0800 Subject: [PATCH 1/9] fix: prevent CNClaim Finalize stuck and scale-in race during migration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes 4 bugs that cause CNClaim Finalize to get stuck and scale-in to select migrating claims: 1. Finalize() stuck when all owned Pods are claimed by another CNClaim — now releases the claimed-by label and completes finalization 2. CNClaimSet scale-in selects claims mid-migration (spec.SourcePod != nil) — now excludes migrating claims from scale-in candidates 3. Sync() Pod NotFound doesn't clear spec.PodName — claim stays in Lost forever with stale podName 4. watchPodChange only triggers reconcile via Pod label — now also triggers for CNClaims referencing the pod via spec.podName Closes #591 Co-Authored-By: Claude Opus 4.6 --- pkg/controllers/cnclaim/controller.go | 82 ++++++++++++++----- pkg/controllers/cnclaim/controller_test.go | 19 +++++ pkg/controllers/cnclaimset/controller.go | 10 ++- pkg/controllers/cnclaimset/controller_test.go | 58 +++++++++++++ 4 files changed, 148 insertions(+), 21 deletions(-) diff --git a/pkg/controllers/cnclaim/controller.go b/pkg/controllers/cnclaim/controller.go index 79de36c6..e5ce4342 100644 --- a/pkg/controllers/cnclaim/controller.go +++ b/pkg/controllers/cnclaim/controller.go @@ -266,6 +266,13 @@ func (r *Actor) Sync(ctx *recon.Context[*v1alpha1.CNClaim]) error { return recon.ErrReSync("pod status may be not update to date, wait", waitCacheTimeout) } c.Status.Phase = v1alpha1.CNClaimPhaseLost + if err := ctx.Patch(c, func() error { + c.Spec.PodName = "" + c.Spec.NodeName = "" + return nil + });
