Description Eric Jones 2015-12-09 22:29:51 UTC
- What is the nature and description of the request?  
As an admin I need the ability to expand the storage setup on a persistent volume, without losing the existing data that I already have. 

- Why does the customer need this? (List the business requirements here)  
The docker images they have pushed to their registry are taking up too much space. A possible fix for this scenario is to increase the size of the registry.

- How would the customer like to achieve this? (List the functional requirements here)  
The ability to expand the Persistent Volume without damaging the data inside the existing PV. 

- Is there already an existing RFE upstream or in Red Hat Bugzilla?  
Not that I could find  

- List any affected packages or components.  
OpenShift
Docker

This is a feature request for "resizing a volume", for which we have a Trello card.

Comment 5 Steve Watt 2016-04-13 17:22:33 UTC
This card is being tracked here - https://trello.com/c/WC1urO9c/138-21-provide-a-means-to-increase-the-storage-capacity-of-a-pv-openshift-online-ops-rfe

It hasn't moved yet as it will only get worked on after the core storage functionality refactoring, storage classes and dynamic provisioning is complete.

Hi Steve,

Do you have a specific bug (or several bugs) or trello(s) that we can put as blocking on this bug? As you indicated that this won't be worked until "core storage functionality refactoring, storage classes and dynamic provisioning is complete."

Comment 7 Steve Watt 2016-08-29 16:12:48 UTC
Eric, I think a better approach is to track the feature card https://trello.com/c/02MHzcR0/272-feature-support-the-ability-to-resize-a-persistent-volume (which is now linked to the work item card in the description) and see which OpenShift release it is scheduled for. At present, it is proposed for OpenShift 3.5, but we have yet to do release planning for that. In reality, we need to start with a Spike to actually figure out how we're going to address this problem. Once we do that, we need to build community consensus around the approach and only once that happens, does the rough timeline regarding when this will land in an OpenShift release, start to take shape.

You can expand persistent volume claims for CNS glusterFS, Cinder, and GCE PD in OCP 3.9. You may need some extra config though as volume expansion is a Technology Preview feature, and hence, is not enabled by default in your OpenShift Container Platform 3.9 cluster.

This bz (RFE) has been identified as a feature request not yet planned or scheduled for an OpenShift release. Due to tooling changes in how we are tracking and planning RFE’s into the OpenShift product we are closing this RFE. 

If this feature is still an active request that needs to be tracked, Red Hat Support can assist in filing and ensuring that the OpenShift PM team has the proper trackers filed in the correct places, as well as provide you with updates as the RFE progress within our planning processes.
