openstackCinder QoS Specs: Putting a Ceiling on OpenStack Storage Noisy Neighbors
Learn how to use OpenStack Cinder Volume Types and QoS specs to cap IOPS, prevent noisy-neighbor contention, and verify where enforcement actually happens.
Back Up Your OpenStack Volumes Without Downtime: Snapshots, Glance, and Automation
Learn how to back up OpenStack Cinder volumes instantly with snapshots, export them to Glance, and automate the process—complete with commands, trade‑offs, and a step‑by‑step example.
Implementing OpenStack Cinder Volume Backups for Disaster Recovery
Learn how to configure OpenStack Cinder Volume Backups to move critical data from block storage to an independent object store for disaster recovery.
Does a client-side timeout cancel in-flight work in OpenStack's Nova, Neutron, and Cinder?
OpenStack has no request-wide cancellation token or deadline propagation standard shared across its services. When a client times out or disconnects, work already accepted by Nova, Neutron, or Cinder generally continues server-side unless it is explicitly aborted through a service-specific action such as Nova's delete or force-delete. The open question is ho
Should Low‑Traffic Workloads Use Boot‑From‑Image or Boot‑From‑Volume in OpenStack?
For a low‑traffic workload the operator wants to minimize monthly expenses while retaining the ability to snapshot and recover instances. The decision hinges on whether to boot instances from the local ephemeral disk (boot‑from‑image) or from a Cinder volume (boot‑from‑volume). Boot‑from‑image avoids per‑GB volume charges and network attachment overhead, but
Incremental backup chain restore blocked by missing parent backup in Ceph backend
Context Cinder incremental backups on the Ceph/RBD backend form a parent-child chain where each child backup depends on its parent for a full restore. The control plane records the relationship, but the backend objects themselves must remain intact. Problem A restore request for a child incremental backup fails when the parent backup has been deleted or its
