Bug detection and triaging in complex storage systems pose unique challenges that distinguish them from general-purpose or SaaS-based software. Unlike conventional code which largely operates in a straightforward user space, storage solutions must seamlessly integrate with the operating system kernel, device drivers, and underlying hardware devices. This tight coupling introduces additional complexity in logging, concurrency, and operational flow. For instance, storage systems often span hundreds of threads and processes, each writing into shared log files without conventional transactional guarantees. Such intricate interactions make it difficult for existing AI-based bug-tracking solutions which are typically trained on general codebases to deliver effective results.  

To address these limitations, we propose a novel approach that supplements the system code with knowledge extracted from high-level integration test cases. These tests, often written in human-readable scripting languages such as Python, capture end-to-end system behavior more effectively than narrowly focused unit tests. By converting the insights from integration tests into a structured knowledge graph, our methodology provides an AI bug-triaging agent with rich contextual understanding of system interactions, inter-process communications, and hardware events. This deeper, scenario-driven perspective empowers the agent to pinpoint and diagnose issues from storage system failures that would otherwise be hidden in the labyrinth of kernel-mode calls, user-mode processes, and low-level device drivers. Our early findings suggest that this targeted fusion of code analysis and integration-test-based knowledge significantly enhances both the speed and accuracy of bug identification in storage software an advancement poised to transform how complex system bugs are tracked and resolved.
