About supporting fio #45

Closed leftgeek closed 2 years ago

leftgeek commented 3 years ago

When I run fio on splitfs, it always fails in _hub_FOPEN("/proc/self/status") and gets NVP_ASSERT(_hub_managed_fileops != NULL) failed!

It seems that the libnvp.so is not loaded, but filebench and other shell commands such as "ls, df" can be intercepted successfully by splitfs.

I also noticed that the filebench code under splitfs is almost unmodified. How should I start to modify fio to run on splitfs?

I have added FIO support to SplitFS. You can pull the latest code from the master branch. It has the details in README about how to run FIO.

Thanks, it worked. Several fio files are missing: lib/output_buffer.h lib/output_buffer.c blktrace.h blktrace.c blktrace_api.h
