I'll take a look, I bet it's an issue from around the time the file

Can you send the exact job you used to create and replay files? Will
make my life easier.
Hi, I'm am running into this issue too.
Here are simple instructions to replicate:
[hdc-write]
filename=/dev/hdc
ioengine=sync
iodepth=1
direct=1
thread=1
continue_on_error=1
read_iolog=trace.log
trace.log:
/dev/hdc add
/dev/hdc open
/dev/hdc write 2045557202944 8192
/dev/hdc close
./fio trace.fio
hdc-write: (g=0): rw=read, bs=4K-4K/4K-4K/4K-4K, ioengine=sync, iodepth=1
fio-2.1.7

OK, so the replay bug here is that you added a filename=. Due to a bug
in the freeing of files logic (fio does do that for iolog loads), we
don't reset this when freeing files. So fio attempts to close 2 files on
exit, boom.
This is fixed in -git as of now. Replay of that file still looks weird,
doesn't look like it actually does that IO. Will debug next...
