Description John Matthews 2020-07-08 12:37:40 UTC

+++ This bug was initially created as a clone of Bug #1854908 +++

Description of problem:

Sometimes a migration may fail as the stage pods are created and stay in Pending as they are unable to mount a PVC due to it being stuck in a Terminating state.

To recreate:
1) Create a Pod that mounts a PVC
2) Create a MigPlan that references the Pod and PVC
3) Delete the PVC while it is mounted to the Pod, PVC will be in terminating
4) Run a migration with the MigPlan

Verified in CAM 1.2.4 stage

Source cluster: 3.11 aws
Target cluster: 4.4 aws
Replication repository: aws s3
PVC storageclass: gp2

1. Deploy application
2. Create migration plan
3. Remove pvc
4. Execute migration plan


The result is that, as expected, the execution failed with this error:
