Description Vikram Goyal 2016-08-07 09:18:30 UTC
Kubernetes admin PVC request should bind to a best-fit PV, instead of first match, to minimize waste.

Comment 1 Ashley Hardin 2016-08-15 18:14:32 UTC
@Jan - I think this section is what needs updated: https://docs.openshift.com/enterprise/3.2/architecture/additional_concepts/storage.html#pvc-access-modes

Can you please confirm? Thanks!

Comment 2 Jan Safranek 2016-08-16 07:42:35 UTC
I would change chapter "Binding" in https://docs.openshift.com/enterprise/3.2/architecture/additional_concepts/storage.html#binding

There is already written "The user will always get at least what they asked for, but the volume may be in excess of what was requested." The change we introduced is to minimize this "excess" - OpenShift binds to the smallest PV that matches all other criteria.

Work in progress: https://github.com/openshift/openshift-docs/pull/2656
