SUSE Storage v1.11.2 Release Notes

This release introduces several improvements and bug fixes that are intended to improve system quality, resilience, stability and security. The documentation is available at SUSE Storage Documentation.

For terminology and context on SUSE Storage releases, see Releases.

Important Fixes

This release includes several critical stability fixes.

Replica rebuild progress fix

Resolved an issue where replica rebuild progress could exceed 100% under unstable network conditions. Progress reporting is now capped at 100%.

For more details, see #12949.

CSIStorageCapacity scheduling enhancement

Introduced a new setting to control CSIStorageCapacity reporting. Previously, compute nodes without SUSE Storage disks incorrectly reported 0 capacity, breaking WaitForFirstConsumer scheduling. With this enhancement, capacity tracking can be configured to avoid rejecting compute nodes in separated compute/storage architectures.

For more details, see #12807.

Improvement

Manager memory optimization

Optimized longhorn-manager Pod informer caching to reduce cluster-wide memory usage.

For more details, see #12771.

Installation

Ensure that your cluster is running Kubernetes v1.25 or later before installing SUSE Storage v1.11.2.

You can install SUSE Storage using a variety of tools, including SUSE® Rancher Prime, Kubectl, and Helm. For more information about installation methods and requirements, see Quick Installation in the documentation.

Upgrade

Ensure that your cluster is running Kubernetes v1.25 or later before upgrading from SUSE Storage v1.10.x or v1.11.0 to v1.11.2.

Users on v1.11.0 who experienced the memory leaks of longhorn-instance-manager pods #12575 are highly encouraged to upgrade to v1.11.2 to receive the permanent fix for the proxy connection leaks.

SUSE Storage only allows upgrades from supported versions. For more information about upgrade paths and procedures, see Upgrade in the documentation.
