无法在RancherOS上调配OpenEBS卷

Question

我使用Rancher v2作为k8s管理平台，并在VMware vSphere上运行RancherOS节点。我手动安装了open-iSCSI，并在工作节点上挂载了一个50 on的卷，以供OpenEBS使用(我必须弄清楚如何在创建节点时自动执行此操作)。我还创建了一个cStor存储类，一切看起来都很好。但是，我还不能让容器使用pvc来配置pv。

我按照以下步骤在RancherOS文档的RancherOS前提条件部分启用OpenEBS。

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

从Rancher OS的github存储库中，发现我们需要创建一个锁定目录，并确保使用以下方式在每次引导时创建此目录

$ mkdir /run/lock
# update cloud-config
#cloud-config
runcmd:
- [mkdir, /run/lock]

引用路径: rancher的github repo。然后在rancher/OS下找到问题号2435
