The steps is is following: 1) oadm manage-node nodex --schedulable=false 2) oadm manage-node nodex --evacuate --force 3) upgrade your OS packages and restart OS 4) oadm manage-node nodex --schedulable=true Additional information:
The current process is to 'drain' a node rather than evacuate, the new command is: oadm drain nodex --force --delete-local-data --ignore-daemonsets Step #1 for master upgrade is not necessary starting with OCP 3.3 as the endpoint will automatically be removed after an API server has been shut down.
Thanks, all. I've created a PR for this: https://github.com/openshift/openshift-docs/pull/3865 Anping Li, can I please ask if you think this fulfills this BZ? As the reporter and QE contact, I would also like to ask if the process in the PR is also accurate, as it's changed since your initial report. Thanks!
I think it is better to add description of atomic-openshift-excluder atomic-openshift-docker-excluder which are used avoiding OCP upgrade during OS upgrade. https://docs.openshift.com/container-platform/3.4/install_config/upgrading/manual_upgrades.html
Sure, I've added another step to the procedure. Can I ask for another look please? Please let me know if the new step should be in a different part of the procedure (if it matters). Thanks.
"Install or update to the following latest available **-excluder* packages ",It should be same version with OCP rather than the latest available . The other part looks good.
OK. I've updated the comment as per Comment 8. Vikram, that's for a different section of the docs, but this could be used for reference for the BZ assignee. If there's anything else for this BZ, let me know, but otherwise, I'll put this onto peer review. Thanks, all.
