Also, are there tools that can cause aborts underneath the file system,= basically something in the mid layer that randomly drops IOs or someth= ing along those lines? I am looking for tests which can fully stress the system exercising the= file system and also check for corruption.=A0 As an aside, I looked at xfstests, from what I could gather, it was sta= rted only for xfs, but there is ongoing work to make it work with ext4(= and thus other posix FS?). If someone can point me to the documentation= for xfstests and what it does, that would help. I could not find much.
