[BUG] apecloud-mysql cluster hscale offline instance then stop and start, pod CrashLoopBackOff
Describe the bug A clear and concise description of what the bug is.
kbcli version
Kubernetes: v1.27.9
KubeBlocks: 0.9.0-beta.23
kbcli: 0.9.0-beta.9
To Reproduce Steps to reproduce the behavior:
- create cluster
kbcli cluster create mysql-cluster --termination-policy=WipeOut --cluster-definition=apecloud-mysql --cluster-version=ac-mysql-8.0.30 --set cpu=500m,memory=0.5Gi,replicas=5,storage=1Gi
- hscale offline instance
kubectl create -f -<<EOF
apiVersion: apps.kubeblocks.io/v1alpha1
kind: OpsRequest
metadata:
generateName: mysql-cluster-hscaleoffinstance-
spec:
clusterRef: mysql-cluster
horizontalScaling:
- componentName: mysql
replicas: 4
offlineInstances: ["mysql-cluster-mysql-0"]
ttlSecondsAfterSucceed: 0
type: HorizontalScaling
EOF
- stop -- start
kbcli cluster stop mysql-cluster --auto-approve
kbcli cluster start mysql-cluster
- See error
