# 2022-06-01-22:33:44+0800 delete the slot of db-pd-2 in cluster 1363424513567494144

- Cause: there's a failure pod in cluster for a long time, the PD pod is unrecoverable.
- Operation: use the delete slot function of advanced statefulset to skip this member.

```bash
# take a backup of current tc
kubectl get tc db -n tidb1363424513567494144 -o yaml > tc_backup.yaml

# edit target tidbcluster resource
kubectl annotate tc db pd.tidb.pingcap.com/delete-slots='[2]' -n tidb1363424513567494144

# wait the upgrade complete
kubectl get po -n tidb1363424513567494144 --watch
```

- Impact:
- Recovery Operation: apply the `tc_backup.yaml` back to the cluste
- Time window:
