2.5. 查找可用的存储设备

流程

1. 使用 OpenShift Data Foundation 标签列出并验证工作程序节点的名称。

   $ oc get nodes -l cluster.ocs.openshift.io/openshift-storage=

   Copy to Clipboard Toggle word wrap

   输出示例：

   NAME       STATUS   ROLES    AGE     VERSION
   worker-0   Ready    worker   2d11h   v1.23.3+e419edf
   worker-1   Ready    worker   2d11h   v1.23.3+e419edf
   worker-2   Ready    worker   2d11h   v1.23.3+e419edf

   Copy to Clipboard Toggle word wrap

2. 登录到用于 OpenShift Data Foundation 资源的每个 worker 节点，并查找您在部署 Openshift Container Platform 时附加的额外磁盘的名称。

   $ oc debug node/<node name>

   Copy to Clipboard Toggle word wrap

   输出示例：

   $ oc debug node/worker-0
   Starting pod/worker-0-debug ...
   To use host binaries, run `chroot /host`
   Pod IP: 192.168.0.63
   If you don't see a command prompt, try pressing enter.
   sh-4.4#
   sh-4.4# chroot /host
   sh-4.4# lsblk

   在本例中，对于 worker-0，可用的 500G 本地设备为 sda, sdc, sde,sdg, sdi, sdk, sdm,sdo。

3. 对于所有其他带有被 OpenShift Data Foundation 使用的存储设备的 worker 节点，重复以上步骤。详情请查看本知识库文章。
