2023 Annual Report: SIG Storage

Current initiatives and Project Health

1. What work did the SIG do this year that should be highlighted?

GA milestones hit

- [2268 - non graceful shutdown](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/2268-non-graceful-shutdown) - v1.28
- [2485 - ReadWriteOncePod PersistentVolume AccessMode](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/2485-read-write-once-pod-pv-access-mode) - v1.29
- [3107 - SecretRef field addition to NodeExpandVolume request](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/3107-csi-nodeexpandsecret) - v1.29
- [3333 - Retroactive default StorageClass assignment](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/3333-retroactive-default-storage-class) - v1.28

Successful progress

- [3751 - Kubernetes Volume Provisioned IO](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/3751-volume-attributes-class) - v1.29
  - The VolumeAttributesClass Alpha feature was introduced in v1.29. This feature proposes an extension to the Kubernetes Persistent Volume API to allow users to change volume attributes after provisioning (for example, for IOPS or throughput).

2. Are there any areas and/or subprojects that your group needs help with (e.g. fewer than 2 active OWNERS)?

• Write more tests; monitor test grid health; work on test framework out of tree; enhance CSI release tools.
• Doc writer to improve docs on CSI side and in general in Storage side.
• We have a weekly issue triage meeting, but would appreciate help with more efficient issue triage and help with fixing the issues.
  • https://github.com/orgs/kubernetes-csi/projects/52/views/3
