Hi,
Running the following fio command in Red Hat 6.1
fio --name=myjob --ioengine=libaio --rw=randrw --bs=8k --numjobs=64 --thread --direct=1 --size=400m --directory=/mnt --rwmixread=50 --rwmixwrite=50 --do_verify=1 --verify=md5 --verify_fatal=1
I got the error message:
myjob: (groupid=0, jobs=1): err=84 (file:io_u.c:1477, func=io_u_queued_complete, error=Invalid or incomplete multibyte or wide character): pid=29170: Thu Jun 13 11:56:04 2013
fio returns 1280 (0x500)
What is the meaning of this error message?
Thank you
Konstantin

It means you got a verification failure, comparing the data read back to
the expected results.

Thank you, Jens for the help.
I already found data corruption errors (CRC and magic headers) in fio output.
