Hi Clayton, We’re running 3.6.1 I believe. It was installed a few weeks ago using OpenShift ansible on the the release-3.6 branch.
We’re running 11 namespaces, 2 nodes, 7 pods, so it’s pretty minimal. I’ve never run this prune. https://docs.openshift.com/container-platform/3.6/admin_guide/pruning_resources.html Is there some log that would help highlight exactly what the issue is?
