Note from the velero logs I'm not seeing an obvious error.

The issue seen with no 'default' is fine.  We don't expect a default, after MigPlan is created we will create the BackupStorageLocation resources.

Confirmed that looks good from Velero logs with below in logs:
"Got backups from backup store" backupCount=0 backupLocation=migstorage-sample-cqvvc controller=backup-sync logSource="pkg/controller/backup_sync_controller.go:184"


After this I don't see further work, beyond the confirmation that Velero is happy with the backupLocation.

I would have expected to see logs from work being done, not seeing that.

I did notice that from the migration output shown above, the migration itself is in the completed state. Are the velero logs attached above for the source cluster or for the destination/target cluster?

Also, are there any velero backup or restore CRDs in either the src or dest clusters?
I wonder if 'velero backup get -n openshift-migration' on src  cluster or 'velero restore get -n openshift-migration' on dest cluster would show anything.

I've never seen a case where a migration moved to a successful Completed state without the velero operations running, so if that's what is happening here, we should probably look at the controller logs too.

Hi

I don't see any backup or restore CRDs in either the source or destination cluster - 

sh-4.4$ ./velero restore get -n openshift-migration
NAME   BACKUP   STATUS   WARNINGS   ERRORS   CREATED   SELECTOR
sh-4.4$ 
sh-4.4$ 
sh-4.4$ 
sh-4.4$ ./velero backup get -n openshift-migration
NAME   STATUS   CREATED   EXPIRES   STORAGE LOCATION   SELECTOR

So if the velero CRDs aren't being created at all, that sounds like a problem with the controller rather than with Velero. It might be helpful to see the controller logs as well as the complete yaml output for the migplan and migmigration.

So it looks like this was a stage migration rather than a final migration. A final migration is a two-pass migration where, in the first pass, PV data is moved over, and in the second pass, everything else comes along. A stage migration only does the "migrate PVs" step, to allow for incremental copying of persistent volumes, which in some cases will significantly shorten final migration times.

In this case, though, you don't have any PVs to migrate, so the stage migration ends up being basically a no-op.

So we need to see the velero logs for that backup. You can use the velero CLI to get them "velero backup get -n openshift-migration migplan-sample-m2f4v" That will show just the logs for the one backup. You can also just grab the velero pod logs, but that will include all backups executed since the velero pod started.

While the original problem stated here isn't really a bug -- we expect there to be no velero action taken for a stage migration with no PVs -- it's confusing, so I've added a warning condition on the migmigration when this situation occurs.
PR is here: https://github.com/konveyor/mig-controller/pull/510

Verified using CAM 1.2 stage

When we run a stage migration using namespace where no PVC exists, a warning is reported in the MigMigration resources telling the user that there is no PVC to execute a "Stage".

This warning is visible in the UI too, marking the migration execution in orange.
