Fixed In Version: 2.4.0
Doc Type: Known Issue
Doc Text:
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

Section Number and Name: 

Describe the issue: 

The following note sould be added:

VMs created from common templates are created with "evictionStrategy: LiveMigrate".
If a VM is using HPP (or any other storage class with AccessModes: ReadWriteOnce), this label should be removed before an upgrade is initiated.

Suggestions for improvement:

Comment 9 Dan Kenigsberg 2020-08-01 18:54:39 UTC
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

Verified the workaround: VM without eviction strategy and runStrategy = 'Always' (4.4.13->4.5.3)
