Important Fixes

This release includes several critical stability fixes.

V1 volumes not operable fix after iscsid restart

Resolved the issue caused by the iscsid restart where volume operations could become stuck or fail, including PVC resize failures.

For more details, see #13411, #13413, and #13383.

Replica rebuild stability fix

Fixed a nil pointer dereference panic in longhorn-instance-manager during replica rebuild, improving rebuild stability under failure conditions.

For more details, see #13129.

Migration engine readiness transition fix

Resolved an issue where the migration engine could be unexpectedly deleted while the target node was still transitioning to ready, which could interrupt migration workflows.

For more details, see #13133.

Recurring trim job deadlock fix

Resolved a deadlock that could cause recurring trim jobs to fail.

For more details, see #13424.

Installation

Due to the upgrade of the CSI external provisioner to v6.3.0, ensure that your cluster is running Kubernetes v1.34 or later before installing SUSE Storage v1.11.3.

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

Due to the upgrade of the CSI external provisioner to v6.3.0, ensure that your cluster is running Kubernetes v1.34 or later before upgrading from SUSE Storage v1.10.x or v1.11.0 to v1.11.3.

Users on v1.11.0 who experienced the memory leaks of longhorn-instance-manager pods #12575 are highly encouraged to upgrade to v1.11.3 to receive the permanent fix for the proxy connection leaks.
