Subject: xfstests ext4/304 failing due to donor inode's i_size == 0
Date: Sun, 18 Oct 2015 22:57:27 -0400 [thread overview]
Message-ID: <20151019025727.GA6676@thunk.org> (raw)
Hi Dmitry,
I was investigating why ext4/304 is failing, and it's due to
defrag-fuzzer returning an error:
defrag-fuzzer: (groupid=0, jobs=1): err=22 (file:ioengines.c:309, func=td_io_que
ue, error=Invalid argument): pid=3207: Sun Oct 18 19:43:57 2015
After instrumenting the kernel, it appears that this is due to donor
inode's i_size being set to 0.
Can you reproduce this faiure? And if it's working for you, what
version of fio are you using? I normally use fio 2.1.3, since newer
versions of fio have caused test regressions that appear to be caused
by fio bugs. I tried fio 2.1.14, it was also failing. I could try
using 2.2.x versions of fio, but as I recall, that set of versions was
were I started running into other test failures caused by fio bugs.
(When I asked Dave Chinner about this a while back, he tod me he was
using 2.1.3 because he had run into regressions caused by vio, and
I've been sticking with fio 2.1.3 for quite a while now.)
Thanks,
- Ted
