System-Call Based Problem Diagnosis for PVFS

Pagination or Media Count:
We present a syscall-based approach to automatically diagnose performance problems, server-to-client propagated errors, and server crashhang 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.
