Why is step 2 done? During this phase hosted engine should be in global maintenance, nothing should migrate it till all the HE hosts are upgraded. Per Sandro: We need to state clearly in the HE section of the upgrade guide that you need to detach the 4.3 storage domain before upgrading the engine to 4.4, and use a dedicated storage domain for the 4.4 hosted-engine deployment. Two reasons: - In an HA environment, other 4.3 HA-hosts are still connected to the 4.3 storage domain. - In HA and non-HA environments, keeping the 4.3 storage domain is necessary for disaster recovery. Here are the current steps to upgrade SHE from 4.3 to 4.4 [1]: Upgrading a self-hosted engine environment from version 4.3 to 4.4 involves the following steps: ==== ... 3 Migrate any virtual machines that are running on the same host as the Manager virtual machine to another host in the same cluster. 4 Place the environment in global maintenance mode 5 Update the 4.3 Manager to the latest version of 4.3 6 Upgrade the Manager from 4.3 to 4.4 7 Upgrade the self-hosted engine nodes, and any standard hosts, while reducing virtual machine downtime. 8 (Optional) Upgrade RHVH while preserving local storage. 9 Update the compatibility version of the clusters 10 Reboot any running or suspended virtual machines to update their configuration 11 Update the compatibility version of the data centers ==== So I will add: 4.1 Detach the 4.3 storage domain before upgrading the engine to 4.4, and use a dedicated storage domain for the 4.4 hosted-engine deployment.

Moving to verified after both Nikolai and Roman signed off. Eli, please do peer review. See comment 5 for the merge request. Peer reviewed, merged into 4.4 branch - RHV Upgrade Guide For any questions regarding working steps, I've verified this flow following https://bugzilla.redhat.com/show_bug.cgi?id=1893385#c5. |
