Feature Overview (aka. Goal Summary)  

Currently vsphere migrated in-tree PVs cannot be resized. It was a VMware limitation that they resolved. The goal of this epic is to allow and document resizing in-tree migrated PVs in OCP.

Goals (aka. expected user outcomes)

Customers who upgraded OCP and have CSI migration enabled want to benefit from VMware improvements.

Test and document in-tree migrated volume resize

Requirements (aka. Acceptance Criteria):

Resize in-tree migrated volumes passes regular resize tests.

Anyone reviewing this Feature needs to know which deployment configurations that the Feature will apply to (or not) once it's been completed.  Describe specific needs (or indicate N/A) for each of the following deployment scenarios. For specific configurations that are out-of-scope for a given release, ensure you provide the OCPSTRAT (for the future to be supported configuration) as well.

Use Cases (Optional):

1. As an OCP user, I want to resize an in-tree PV that has been migrated to CSI.

Questions to Answer (Optional):

Is it testonly? — yes

Out of Scope

Limited to what is delivered by vmware

Background

In-tree migrated volumes were limited in terms of resize, vmware added support in their driver, we need to align with them by testing and documenting this feature.

Customer Considerations

Only applies to vsphere customers who went through CSI migration.

Documentation Considerations

Remove resize limitation for in-tree and document how to update the thin storage class.

Interoperability Considerations

vsphere only
