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
