Cluster Migration with Data Movement

Hi!

I have two OKD cluster and want to migrate an application between them. Both clusters run rook-ceph with the same storage classes. I am using an additional Minio instance as backup storage. Both OKD cluster have access to the Minio instance.

I was able to successfully migrate the application using the file system backup, but I am not able to get it working with data movement. The backup itself works without issue but when I try to restore in the second cluster I get the following error

Errors:
  Velero:     <none>
  Cluster:    <none>
  Namespaces:
    projects-xwiki-restore:  error preparing persistentvolumeclaims/projects-xwiki-restore/data-xwiki-mysql-0: rpc error: code = Unknown desc = fail get DataUploadResult for restore: xwiki-restore-23: no DataUpload result cm found with labels velero.io/pvc-namespa

Should Data Movement between clusters work?

Opening an issue from a discussion, because I got no further answers in the discussions section and I was told that this should work. Please take a look at the linked discussion for detailed description and log output.

Would be great if you could help me out here.

Thanks!

Could you share velero log bundle by running velero debug?

[raynay-r]

Sure. Here are the bundles from the source and target cluster:

bundle-source-cluster.tar.gz
bundle-target-cluster.tar.gz

The restore forgejo-restore-1 in the debug bundle was created in 2024-09-14, but the log started from 2024-10-03, cannot find any useful information related to the failed restore.
Could you create a new restore and collect the debug bundle again?

[raynay-r]

I created a new backup with the name "forgejo-backup-10" on the source cluster and a restore with the name "forgejo-restore-11" on the target cluster an could reproduce the same error again. Here are the bundles:
bundle-target-cluster.tar.gz
bundle-source-cluster.tar.gz
