Help : Facing this when i trigger FIO from command line :"fio: file hash not empty on exit"

[sampath rapaka]

Hello all

I am trying to trigger FIO from command line using below command.

But i was thrown below error message.

Error:
fio: pid=13800, got signal=11
fio: file hash not empty on exit

Command line command:

fio --output=test_1 --name=test_1 --filename=/dev/md0
--ioengine=libaio --direct=1 --norandommap --randrepeat=0
--refill_buffers --time_based --runtime=180s --blocksize=8k
--rw=randrw --rwmixwrite=67 --iodepth=32 --overwrite=1

There is something wrong in the command I have run ?

regards
sampath

Can you mention the version of fio you are using ?

Can you double check you didn't had an OOM message from the kernel ?

fio --version
fio-2.0.15

I have not seen any Issues with Memory. I had run other fio test from
config file, It went smoothly.

First try a make clean && make and see if it reproduces. If it does,
then edit the Makefile and remove the -O3 in there. Then make clean &&
make. Now do ulimit -c10000000000 and reproduce the issue. That should
give you a core dump file. Then do:

# gdb fio core

and type 'bt' and send the full output here.

Thanks for the reply. Once I get a test machine i will try it and
update the back trace.
