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?


Thanks,

Joel
