我将Rancher v2用作k8s管理平台，并在VMware vSphere上运行RancherOS节点。我手动安装了open-iSCSI，并在工作节点上安装了50GB的卷，供OpenEBS使用（必须弄清楚如何在创建节点时自动执行该操作）。我还创建了一个cStor存储类，一切看起来都不错。但是，我无法获得使用pvc来配置pv的容器。

我已按照以下步骤在OpenEBS文档中针对RancherOS的Prerquisitie部分中的RancherOS上启用iSCSI。
sudo ros s up open-iscsi
sudo ros config set rancher.services.user-volumes.volumes [/home:/home,/opt:/opt,/var/lib/kubelet:/var/lib/kubelet,/etc/kubernetes:/etc/kubernetes,/var/openebs]
sudo system-docker rm all-volumes
sudo reboot

在Rancher OS的github存储库中，发现我们需要创建一个锁目录，并确保每次启动时都使用以下方式创建该目录
$ mkdir /run/lock
# update cloud-config
#cloud-config
runcmd:
- [mkdir, /run/lock]
