openstack/cinder — Week of 2026-09-26

Driver work. The Pure Storage driver picked up the largest change of the week, tightening SDK response checking on volume and snapshot operations at roughly 400 lines added. A companion fix enforces exclusivity between replicated and non-replicated consistency groups so the two cannot be mixed. Elsewhere on the driver side, the IBM Spectrum Virtualize family now skips iSCSI IP discovery when FC is the configured protocol, and the Hitachi driver ticked its in-code version string.

Eventlet retreat. Two related patches remove eventlet usage from volume_utils and improve type handling around utils.tpool_wrap(), continuing the long-running effort to shed eventlet from the codebase. Both landed on master and on a stable branch as paired backports.

API reference. Three documentation patches clean up the api-ref: corrections to the qos-specs docs, an explanation of why consistency groups are deprecated, and fixes to the clusters API docs.
