The block storage service in OpenStack , code named Cinder, has been extensively developed at every OpenStack release to come with new additions to support multiple storage vendors. As Cinder has become the default service for persistent storage in OpenStack, managing volumes for virtual machines has been simplified. This covers more operational commands for different use cases, including:
- Recovering instances due to hypervisor failure or instance termination events by attaching volumes to new ones.
- Resizing volumes size based on storage array capacity and flavor needs.
- Storage backup enhanced by the volume snapshot option.
- Creating volumes from snapshots.
- Enhanced block storage capabilities including quality of service, live migration, and performance requirements such as latency and input/output storage throughput. This can be adjusted depending...
