Description Sergio 2019-12-13 16:09:12 UTC 
Description of problem:
When "move" action is selected for a glusterfs pvc migration, if there is no OCS4 installed in the target cluster, a PvWarnNoCephAvailable warning is displayed.

Version 1.0.1 osbs registry:

    image: image-registry.openshift-image-registry.svc:5000/rhcam-1-0/openshift-migration-controller-rhel8@sha256:e2c3cbb61157605d8246496f77c76b9b2950eb951bd0a63d4f8e3ae6f1884c2c


How reproducible:
Always

Steps to Reproduce:
To reproduce it, we don't actually need to migrate or prepare a cluster for "move" action. We only need to create the migration plan.

1. Install App Migration with target cluster without OCS4 (ceph), and source cluster with OCS3 (gluster)
2. Create a MigPlan of an application using glusterfs volume from source to target, select "move" action.


Actual results:
After the MigPlan creation, a warning is shown, saying that it's recommended to use OCS4 storage classes, and that it will be used the default storage class instead.

Expected results:
Destination storage classes don't make much sense talking about "move" action. No warning should be displayed if the selected action is "move" and not "copy".

This has been fixed in https://github.com/konveyor/mig-controller/pull/387
It's on both master and the 1.1 release branches.
Comment 6 Sergio 2020-05-11 10:23:27 UTC 
Verified using CAM 1.2 stage


No warnings when "move" action:
