linstor-controller run-migration - failed to create secret Request entity too large: limit is 3145728 about helm-charts

[WanzenBug]

Looks like the backup of the internal resources before the migration is too large to fit into the k8s secret. In this case you have to manually create a backup of the resources:

$ mkdir linstor-backup
$ cd linstor-backup
$ kubectl api-resources --api-group=internal.linstor.linbit.com -oname | xargs --no-run-if-empty kubectl get crds -oyaml > crds.yaml
$ for CRD in $(kubectl api-resources --api-group=internal.linstor.linbit.com -oname); do
$   kubectl get "${CRD}" -oyaml > "${CRD}.yaml"
$  done

This should leave you with the above mentioned .yaml files on your local machine.

Then, simply create an empty secret like this:

$ kubectl create secret generic linstor-backup-for-linstor-controller-67b986477c-rx9zl --type piraeus.io/linstor-backup

Afterwards, the migration should start
