销毁tidb cluster 之后，再次部署tidbcluster后发现 tikv都是pending，describe发现如下

<wiz_code_mirror><pre class=" CodeMirror-line " role="presentation"> Warning  FailedScheduling  <unknown>          tidb-scheduler  0/4 nodes are available: 1 node(s) had taints that the pod didn't tolerate, 2 node(s) had volume node affinity conflict.</pre>
    <pre class=" CodeMirror-line " role="presentation"> Warning  FailedScheduling  <unknown>          tidb-scheduler  0/4 nodes are available: 1 node(s) had taints that the pod didn't tolerate, 2 node(s) had volume node affinity conflict.</pre>
    
    <pre class=" CodeMirror-line " role="presentation"> Warning  HAScheduling      70s (x2 over 70s)  tidb-scheduler  pods "tidb-cluster-tikv-3" not found</pre></wiz_code_mirror>

1个节点存在pod无法容忍的污染，2个节点存在卷节点亲和冲突

是之前数据卷中的数据没清理导致的

删除之前的数据

<wiz_code_mirror><pre class=" CodeMirror-line " role="presentation">kubectl get pv -l app.kubernetes.io/namespace=tidb -o name | xargs -I {} kubectl patch {} -p '{"spec":{"persistentVolumeReclaimPolicy":"Delete"}}' && \</pre>
    
    <pre class=" CodeMirror-line " role="presentation">kubectl delete pvc --namespace tidb --all</pre></wiz_code_mirror>

删除之前的数据后 ，再重新 helm install tidb-cluster
