Documentation error in “Workers in VPC clusters”: incorrect oc drain command #193
Description
Which topic are you reporting about?
https://cloud.ibm.com/docs/openshift?topic=openshift-host-maintenance&locale=en
What do you think needs to be updated?
I found an issue in this document.
Specifically, in the “Workers in VPC clusters” section, the command is written as oc drain, but the correct command should be oc adm drain.
In addition, in many cases oc adm drain without additional options cannot successfully evict or move Pods.
I manage a cluster running IBM Cloud Pak for Data (CP4D), and in my case, I had to run the following command to complete the maintenance successfully:
oc adm drain <worker_id> --force --delete-local-data --ignore-daemonsets
Users rely heavily on the documentation you provide when performing operational tasks.
I would strongly appreciate it if the procedures were verified and validated in real environments before being published.
Anything else?
Regarding this issue, I have already reported it to the support center under Case .
I was advised by the support team to create a GitHub issue for this matter.
