Cause:
VMs using HPP (or any other storage class with AccessModes: ReadWriteOnce), and have evictionStrategy: LiveMigrate configured
Consequence:
After OCP upgrade, nodes will remain in "Ready,SchedulingDisabled" state as these VMs cannot be live migrated.
Workaround (if any):
Remove evictionStrategy: LiveMigrate from VMs using HPP (or any other storage class with AccessModes: ReadWriteOnce)
Result:
Nodes will be in "Ready" state after OCP upgrade

@Ruty, can you please update the 'doc text' field? *** Bug 1859129 has been marked as a duplicate of this bug. *** @Adam Litke Can you please review this PR: https://github.com/openshift/openshift-docs/pull/24172 Preview build: https://bz-1857788--ocpdocs.netlify.app/openshift-enterprise/latest/virt/upgrading-virt.html#how-openshift-virtualization-upgrades-affect-your-cluster This is the Doc bug. Where do we track the production one? VMs with HPP or SR-IOV should not have LiveMigration eviction, and should probably have runStrategy:Always by default. Please see bug 1858777 @Ruth Can you please review this PR: https://github.com/openshift/openshift-docs/pull/24172 Please add fixed in version Verified the workaround: VM without eviction strategy and runStrategy = 'Always' (4.4.13->4.5.3) Reviewed the PR, moving to verified. Docs PR is now merged. Moving bug to Release Pending. Fix is published in the customer-facing documentation: https://docs.openshift.com/container-platform/4.5/virt/upgrading-virt.html#how-openshift-virtualization-upgrades-affect-your-cluster. Moving bug to Closed + Current Release. |
