Behavior-based problem localization for parallel file systems
Michael P. Kasick, Rajeev Gandhi, Priya Lakshmi Narasimhan · 2010
We present a behavior-based problem-diagnosis approach for PVFS that analyzes a novel source of instrumentation—CPU instruction-pointer samples and function-call traces—to localize the faulty server and to enable root-cause analysis of the resource at fault. We validate our approach by injecting realistic storage and network problems into three different workloads (dd, IOzone, and PostMark) on a PVFS cluster. 1
