Expanding cluster-wide storage:
Cluster-wide storage is expanded by adding allocating, formatting, and configuring additional physical volumes.
Quotas
With per-project volumes, quotas will be enforced by the volume size
Use cases:
- Site administrator can deploy (and re-deploy) cluster storage system
- Cluster administrator can create, expand, and delete per-project volumes
- Project administrators can deploy services that use project storage
- Project administrators can view project storage quotas and usage
- Project administrators can request storage increases
