Is there some benchmark which can do fs or io stress test and verify the test file integrity at the same time, to ensure the written file correct store in disk?

I have this question because a member report some file integrity issues during their mmc card driver developing.

The xfs test suite can do a bunch of that, you should certainly use that, but you might also need something else in addition.

Thanks Arnd!

Is this test case https://en.opensuse.org/SDB:XFStests?

That's the one I meant, yes.

and what's else in addition?

I don't know. See what this does for you first, and what's still missing afterwards.

Thanks for suggestion! Just found the normal case, iozone also provide the integrity checking. That was the first choice by the member.

Thanks Alex

Try stress-ng[1] with the --io* cmdline options.
