openstack/cinder — Week of 2026-09-12

Driver work. NetApp took the lion's share, led by a rework of pool stats collection for the NFS/NVMe driver aimed at update efficiency, alongside disabling clone_across_pools and a fix for iSCSI target LIF pagination. IBM Storwize (SVf) gained support for extending a volume that has snapshots, and the Lightbits driver stopped leaking its JWT into debug logs. On the RBD side, volume reimage now preserves existing snapshots rather than discarding them.

Data-path fixes. A notable correctness fix lands for incremental backup restores, where a chain could previously restore as zeroed data. Image upload also stops sending an empty properties={} to Glance, and non-default qemu process limits can now be applied when Cinder invokes qemu — a long-pending change finally merging after multiple years in review.

Release plumbing. Three small patches cut the stable/2026.2 branch from master, updating .gitreview and TOX_CONSTRAINTS_FILE accordingly.
