I've updated the Product to MTV, since you're apparently not using VMIO API. In MTV 2.2, the interval is not set in HCO or VMIO, because we don't use VMIO anymore. So, we need to update the documentation. @slucidi, could you please explain how to set the interval ? The precopy interval is now set as an environment variable on the forklift-controller pod's `controller` container. In order to adjust it, you need to add `PRECOPY_INTERVAL` with a value in minutes to the `env` section of the `controller` container definition on the `forklift-controller` deployment, or add the key `PRECOPY_INTERVAL` with a value in minutes to the `forklift-controller-config` config map and restart the controller pod.
Example of setting the environment variable on the deployment:
kind: Deployment
apiVersion: apps/v1
metadata:
name: forklift-controller
namespace: konveyor-forklift
<...>
spec:
template:
spec:
restartPolicy: Always
serviceAccountName: forklift-controller
schedulerName: default-scheduler
terminationGracePeriodSeconds: 10
securityContext: {}
containers:
- resources:
limits:
cpu: 500m
memory: 800Mi
requests:
cpu: 100m
memory: 350Mi
terminationMessagePath: /dev/termination-log
name: controller
command:
- /usr/local/bin/manager
env:
- name: PRECOPY_INTERVAL
value: 60
<...>
Example with the forklift-controller-config config map:
kind: ConfigMap
apiVersion: v1
metadata:
name: forklift-controller-config
namespace: konveyor-forklift
<...>
data:
PRECOPY_INTERVAL: '60'
WORKING_DIR: /var/cache/inventory
Thanks @slucidi for providing this information (comment #2) Both options were checked and the interval time between precopies has been changed accordingly. I noticed that the PRECOPY_INTERVAL environment variable on the `forklift-controller` deployment is what counts in case of PRECOPY_INTERVAL is set in both places (`forklift-controller` deployment and `forklift-controller-config` configMap) Could you please confirm this is expected? Yes, that is expected. Changes merged. |
Description of problem: Looks like the interval time between precopies in warm migration stays 60 minutes, although configmap/vm-import-controller-config was patched oc command to change the interval time: $ oc patch configmap/vm-import-controller-config -n openshift-cnv -p '{"data": {"warmImport.intervalMinutes": "3"}}' configmap/vm-import-controller-config patched $ oc get configmap/vm-import-controller-config -nopenshift-cnv -oyaml apiVersion: v1 data: warmImport.intervalMinutes: "3" kind: ConfigMap metadata: creationTimestamp: "2021-10-05T08:55:09Z" name: vm-import-controller-config namespace: openshift-cnv resourceVersion: "7858476" uid: b34163e4-cdb6-479e-9d4f-db55baa1f46f $ oc describe plan mig-plan-warm ...
