在本地尝试动态创建PV时，遇到预绑定插件“VolumeBinding”超时问题。错误发生在将PersistentVolumeClaim放入StatefulSet中。问题根源在于OpenEBS LocalPV的访问模式设置。解决方案涉及理解并正确配置ReadWriteMany和ReadWriteOnce访问模式，以确保StatefulSet中每个容器对数据的独占访问。

需求

在本地实现动态pv，创建一个stateful set，使用volumeClaimTemplates来申请存储
1、安装openebs，只安装本地的hostpath,默认的hostpath是/var/openebs/local

sudo mkdir -p /var/openebs/local
sudo chmod -R 777 /var/openebs/local
helm repo add openebs https://openebs.github.io/charts
helm install openebs openebs/openebs -n openebs --create-namespace \
	--set legacy.enabled=false \
	--set ndm.enabled=false \
	--set ndmOperator.enabled=false \
	--set localprovisioner.enableDeviceClass=false \
  --set localprovisioner.basePath=/var/openebs/local
# 查看pods
-> % kubectl get pods -n openebs
NAME                                           READY   STATUS    RESTARTS   AGE
openebs-localpv-provisioner-6f686f7697-dvjvb   1/1     Running   0          2m16s

2、创建StorageClass,默认的是openebs-hostpath

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: sc-file-hdd
  annotations:
    openebs.io/cas-type: local
    cas.openebs.io/config: |
      - name: StorageType
        value: hostpath
      - name: BasePath
        value: /var/openebs/local
provisioner: openebs.io/local
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer

-> % kubectl get sc
NAME                 PROVISIONER                RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
openebs-hostpath     openebs.io/local           Delete          WaitForFirstConsumer   false                  12m
sc-file-hdd          openebs.io/local           Delete          WaitForFirstConsumer   false                  68s
