Yao -- You filed a similar BZ [1] which is being addressed by another writer. Does this warning cover your concerns here? [2] "To prevent control plane nodes from autorebooting after machine config changes are applied, you must pause the autoreboot process by setting the `spec.paused` field to `true` in the machine pool config." Michael [1] https://bugzilla.redhat.com/show_bug.cgi?id=1886712 [2] https://github.com/openshift/openshift-docs/pull/26829/files#diff-0301ee03744fc7c0a41c613967fe9a86f19a8089bbc40e7a4ed15b17bd35abbeR42-R45 Yao -- I added the first sentence to the note I mentioned in comment 2: [IMPORTANT] ==== Changes to the machine configuration cause automatic nodes reboots. To prevent control plane nodes from autorebooting after machine config changes are applied, you must pause the autoreboot process by setting the `spec.paused` field to `true` in the machine pool config. ==== Please take a look. Thank you. https://github.com/openshift/openshift-docs/pull/27118 Hi Michael, This is Judith. Thanks a lot for your support on this bug. We see that the product documentation has been updated(https://docs.openshift.com/container-platform/4.6/architecture/control-plane.html#understanding-machine-config-operator_control-plane). however, the sentence "Changes to the machine configuration cause automatic nodes reboots." is missing ? Can you pls also include that ? It's also important. Regards, Judith Also, after "you must pause the autoreboot process by setting the `spec.paused` field to `true` in the machine pool config.", can we add something like "Please refer to the section of "Disabling Machine Config Operator from automatically rebooting (https://docs.openshift.com/container-platform/4.6/support/troubleshooting/troubleshooting-operator-issues.html#troubleshooting-disabling-autoreboot-mco_troubleshooting-operator-issues)""? It will make customers easier to understand how to pause/unpause. Judith -- I added a reference to the "Disabling Machine Config Operator from automatically rebooting" section (we are not allowed to add links to the docs at the level where the note is). However, this section was added in 4.5 and does not appear in 4.4; also, the `spec.paused` field is not mentioned in the 4.4 docs. Would it be acceptable to make these changes in 4.5+? Michael https://github.com/openshift/openshift-docs/pull/27118/files Hi Michael, Please go ahead. Thank you for your quick actions! I commented on the PR and tagged some MCO folks for additional input.
