错误描述：

打印日志：

kubectl describe pod ks-jenkins-7fcff7857b-gh4g5 -n kubesphere-devops-system

日志描述如下：

解决

日志我是在节点 k8s-node1打印的，根据日志描述去到了 k8s-node2 看看/var/openebs/local/pvc-3b0a8158-60d4-4b09-9a61-199207575e67这个目录是否存在，发现/var/openebs/local目录下没有pvc-3b0a8158-60d4-4b09-9a61-199207575e67这个目录，那就创建一个

sudo mkdir -p /var/openebs/local/pvc-3b0a8158-60d4-4b09-9a61-199207575e67
sudo chmod 755 /var/openebs/local/pvc-3b0a8158-60d4-4b09-9a61-199207575e67

回到主节点再次查看状况，已经正常了
