VAST CSI Driver 2.7.1 Release Notes

VAST CSI Driver 2.7.1 has been released in October 2026. This release includes:

Enhancements

VCSI-679: Added an ability to set the NFS protocol version that the driver uses when handling deletions on a VAST cluster with Trash Folder Access disabled. To do so, specify the deletionMountOptions option in the storage class definition (together with deletionVipPool and deletionViewPolicy). For example:
- To use NFSv3:
  deletionViewPolicy:
  deletionVipPool:
  deletionMountOptions: vers=3
- To use NFSv4:
  deletionViewPolicy:
  deletionVipPool:
  deletionMountOptions: "vers=4.2,proto=tcp"
  If the deletionMountOptions option is not specified, the driver uses NFSv3 for legacy local-mount deletions.
Operator: kube-rbac-proxy sidecar moved from docker.io/kubebuilder/kube-rbac-proxy to quay.io/brancz/kube-rbac-proxy (digest-pinned). Air-gap must mirror the new image.
VastExtensions gRPC requires TLS on TCP and Unix. Charts generate a self-signed serving certificate and reuse it on upgrade.
Extensions manager image ships the vcsi CLI at /usr/local/bin/vcsi.

VCSI-676: Resolved an issue that could cause an upgrade from 2.6.5-HF6, 2.6.5-HF7, 2.6.5-HF8 to 2.7.0 to fail due to volume name format discrepancy in manually created storage classes.
VCSI-662: Eliminated a potential VAST CSI conroller memory leak that could occur when running with verifySsl=false in the driver's Helm chart.
