Feature request: Allow to configure copyrate/cleanrate on IBM Spectrum Virtualize systems #404

Open TGerisch opened 2 years ago

Cleaning and background copying should be configurable, as it has massive impact on the storage system. In fact, a flash copy mapping with a copy rate > 0 will always end up in a independent copy of the source volume, while a copy rate of zero makes the target a snapshot, which stores only deltas. Cleaning becomes important when snapshots with dependencies are being deleted.

@TGerisch this feature is on our CSI driver road map. We will update once we will know on which version we will introduce this feature.
