System-Call Based Problem Diagnosis for PVFS
In: DTIC (2009)
Abstract: We present a syscall-based approach to automatically diagnose performance problems, server-to-client propagated errors, and server crash/hang problems in PVFS. Our approach compares the statistical and semantic attributes of syscalls across PVFS servers in order to diagnose the culprit server, under these problems, for different file-system benchmarks-dd, PostMark and IOzone-in a PVFS cluster.
