Try to install Longhorn V1.5.1 via Rancher Apps but replace the image repository from rancher mirror: rancher/mirrored-longhornio- to longhornio/, the installation is successful.

Still need wait QA further verification and mirror images release: rancher/image-mirror#418

verify is passed this PR as follow step

The test steps

1. Create pod_with_pvc. https://raw.githubusercontent.com/longhorn/longhorn/master/examples/pod_with_pvc.yaml
2. Create orphaned data.
   SSH to one of the nodes and copy the contents of one replica directory,
   e.g., pvc-abc-…012, to a new directory named pvc-abc-…013. This will make pvc-abc-…013 an orphaned replica.
3. Deploy a statefulSet and attach to the volume. https://raw.githubusercontent.com/longhorn/longhorn/master/examples/statefulset.yaml
4. Validate that the volume is created and attached to the pod properly in the Longhorn GUI.
5. Validate the pod is mounted properly.
6. Scale down and up the statefulSet to check volume detach and attach is working fine.

@roger-ryao have you tested the upgrade from the previous rancher chart? https://github.com/longhorn/longhorn/wiki/Release-Test-Plan---1.5.1 cc @khushboo-rancher

upgrade from the previous rancher chart?

Hi @innobead :
I haven't tested the upgrade from the previous Rancher chart yet. Let me check it.

Should do the same as you have done at #2780 (comment).

• Fresh installation
• Uninstallation
• Upgrade from v1.4.2 - > v1.5.1
• Upgrade from v1.4.3 - > v1.5.1

@PhanLe1010 I've update the PR to include the new CRD: VolumeAttachment.

I also refer to Roger's test steps to do the upgrade testing from 1.4.2 to 1.5.1, and doing some tests:

1. Install LH 1.4.2 in Rancher 2.7
2. Deploy Pod and related PVC: https://raw.githubusercontent.com/longhorn/longhorn/master/examples/pod_with_pvc.yaml
3. Writing some data into the mount point
4. Upgrade to LH 1.5.1 in Rancher
5. Deploy StatefulSet: https://raw.githubusercontent.com/longhorn/longhorn/master/examples/statefulset.yaml
6. Make sure all of the workloads works well
   • volumes could attach to the node
   • data is intact after upgrading
   • new workload could be deployed normally
   • Scale down and up the statefulSet to check volume detach and attach is working fine
