pkg/schedule/checker/rule_checker.go

-				ruleCheckerRemoveOrphanPeerCounter.Inc()
-				return operator.CreateRemovePeerOperator("remove-orphan-peer", c.cluster, 0, region, orphanPeer.StoreId)
+				checkerCounter.WithLabelValues("rule_checker", "remove-orphan-peer").Inc()
+				return operator.CreateRemovePeerOperator("remove-unhealthy-orphan-peer", c.cluster, 0, region, orphanPeer.StoreId)


use "remove-unhealthy-orphan-peer" and "remove-disconnected-orphan-peer" to distinguish

lhy1024 · 2023-11-01T10:42:00Z

pkg/schedule/checker/rule_checker.go

-			// down peer's store should be down.
-			if !c.isStoreDownTimeHitMaxDownTime(pinDownPeer.GetStoreId()) {
+			// down peer's store should be disconnected
+			if !isDisconnectedPeer(pinDownPeer) {


use isDisconnectedPeer rather than isStoreDownTimeHitMaxDownTime, because we use stricter check in isDisconnectedPeer
