Aug 1, 2025This month focused on expanding encrypted volume test coverage and improving test documentation to reduce encryption-related risk and accelerate validation in production. In the longhorn-tests repository, we delivered enhanced test coverage for encrypted volumes, including online expansion of encrypted RWO volumes, stability during node reboots for encrypted RWO/RWX, and negative testing for instance-manager crashes with encrypted volumes. We also updated test documentation and tagging for DR volume negative tests to clarify procedures and link related issues. These efforts increase reliability, enable faster regression detection, and provide clearer guidance for future work across encryption scenarios.
