Reached out to Bobby for clarification on the problem descrption and the vesions the BZ applies to. Created PR --> https://github.com/openshift/openshift-docs/pull/43386 Questions still pending: - Is this the best place to add this info? - Is this only applicable to bare metal and vsphere? - Which versions does this apply to? Created on master for now to start the conversation. Got information from engineering (Ben Nemec) about my questions. "This does not apply to baremetal. It's not a problem to install multiple clusters in a subnet on that platform in any supported release. The only ones where this is a concern are vsphere, openstack, and ovirt, and those should also be fixed in 4.11 by openshift/machine-config-operator#3016 Also note that there is a way to safely run multiple clusters on a subnet. The process described in https://access.redhat.com/solutions/6450581 needs to be followed to ensure there are no conflicts. This does only apply to IPI, so we don't want to mention it in any UPI docs." Closing the PR and opening one in 4.10, since this is fixed in 4.11 (main). Created new PR --> https://github.com/openshift/openshift-docs/pull/43599 @bmehra the new PR is up, please check it out when you can. I've also requested review from Ben Nemec directly on the PR SME review complete. Requesting QE review -- It's not Amit's team. Asking Xiaoli Tian QE assigned. Requesting Peer review as well, no merging yet. While on my search for QEs, found out there had been a similar PR before for another BZ that was never merged: https://github.com/openshift/openshift-docs/pull/35316 https://bugzilla.redhat.com/show_bug.cgi?id=1886450 Talked to Donna DaCosta about it, and the SME that was helping her get the content right, Janos Bonic. There's still a bit of a conundrum about what's needed where: Ben Nemec said this applies to 4.10 and earlier, for Openstack, vSphere, and RHV IPI, but in Donna's PR it seems the fix isn't applicable for 4.10, and that Openstack is not affected. Donna's gracefully agreed to keep working on her PR to get this fixed. On my side, I talked to Janos to put him in contact with Ben so that they can discuss and come with a plan for this BZ from the eng point of view. Janos will be busy for the next 2 weeks on a release but should be available afterwards. I suggest my PR to be closed and this BZ marked as duplicate. Will consult with the DPM. OpenShift has moved to Jira for its defect tracking! This bug can now be found in the OCPBUGS project in Jira. https://issues.redhat.com/browse/OCPBUGS-9109 |
