Epic Goal*
Develop tooling to support migrating CNS volumes between datastores in a safe way for Openshift users.
As a first version, we develop a CLI tool that is shipped as part of the vsphere CSI operator. We keep this tooling internal for now, support can guide customers on a per request basis. This is to manage current urgent customer request, a CLI tool is easier and faster to develop it can also easily be used in previous OCP releases.
Ultimately we want to develop an operator that would take care of migrating CNS between datastores.
Why is this important? (mandatory)
Often our customers are looking to migrate volumes between datastores because they are running out of space in current datastore or want to move to more performant datastore. Previously this was almost impossible or required modifying PV specs by hand to accomplish this. It was also very error prone.
Scenarios (mandatory)
As a admin - want to migrate all my PVs or optional PVCs belonging to certain namespace to a different datastore within cluster without potentially requiring extended downtime.
- I want to move volumes to another datastore that has better performances
- I want to move volumes to another datastore current the current one is getting full
- I want to move all volumes to another datastore because the current one is being decommissioned.
Dependencies (internal and external) (mandatory)
- We depend on latest version of vCenter to accomplish this. So customer must be running latest version of vCenter - https://docs.vmware.com/en/VMware-vSphere/7.0/rn/vsphere-vcenter-server-70u3o-release-notes/index.html and https://docs.vmware.com/en/VMware-vSphere/8.0/rn/vsphere-vcenter-server-802-release-notes/index.html
- We also depend on an environment where we can reasonable test this.
What items must be delivered by other teams/groups to enable delivery of this epic.
Contributing Teams(and contacts) (mandatory)
Our expectation is that teams would modify the list below to fit the epic. Some epics may not need all the default groups but what is included here should accurately reflect who will be involved in delivering the epic.
- Development -
- Documentation -
- QE -
- PX -
- Others -
Acceptance Criteria (optional)
Provide some (testable) examples of how we will know if we have achieved the epic goal.
Drawbacks or Risk (optional)
Reasons we should consider NOT doing this such as: limited audience for the feature, feature will be superseded by other work that is planned, resulting feature will introduce substantial administrative complexity or user confusion, etc.
Done - Checklist (mandatory)
The following points apply to all epics and are what the OpenShift team believes are the minimum set of criteria that epics should meet for us to consider them potentially shippable. We request that epic owners modify this list to reflect the work to be completed in order to produce something that is potentially shippable.
- CI Testing - Basic e2e automationTests are merged and completing successfully
- Documentation - Content development is complete.
- QE - Test scenarios are written and executed successfully.
- Technical Enablement - Slides are complete (if requested by PLM)
