2026 22:17:53 +0000 Subject: [PATCH 3/5] Refactor Longhorn API client based on review feedback - Remove LonghornClient struct, use direct parameters - Make type constants public (LonghornNodeType, LonghornSettingType, LonghornVolumeType) - Remove cap on replica count - Return error when no Longhorn nodes found - Make namespace a parameter to getReplicaCount - Replace testing.T with logrus for logging - CreateVolume now returns pointer to volume and registers cleanup - Add comment explaining data engine v1 - Add comment justifying error ignore in ValidateVolumeActive - Improve ValidateSettings to check for valid value fields - Remove redundant ValidateVolumeInRancherAPI and ValidateDynamicConfiguration - Add polling to validateLonghornPods - Fix ingress check order in validateLonghornService - Remove TestLonghornUIDynamic test - Update test to use refactored API functions Co-authored-by: slickwarren <16691014+slickwarren@users.noreply.github.com> ---
