Configurations
Storage configurations
Storage tier, capacity, provider support, and current workflow behavior for storage changes.
Storage configuration is managed separately from cluster shape.
What can be configured
The current Storage tab lets operators change:
- storage tier
- storage capacity per node
The selected storage settings affect the effective monthly profile price.
Control-plane behavior
When a storage change is queued, the workflow compares:
- current storage tier
- current effective capacity
- next requested capacity
- the monthly price implied by the new selection
If nothing changed, the route skips enqueueing and reports that there are no storage changes to queue.
Provider-specific rule
Current provider behavior:
- GCP storage changes can only increase disk size
- GCP storage changes use backup-driven migration, so the control plane creates a fresh backup and restores into the larger target shape during controlled downtime
- shrinking disk size on GCP is rejected before workflow enqueue
- AWS storage changes are currently blocked until backup-driven migration exists for AWS
Operational notes
- storage and cluster size are priced together in the product model
- storage changes become visible through durable control-plane state after workflow convergence
- allocation history remains the source of truth for effective storage history used by billing and change views
