I'm afraid I can't reproduce the problem with a post 3.0 fio build:
sudo -s
echo -e "0 511 zero\n511 1 error" | dmsetup create errorend
fio --exitall_on_error --direct=1 --bs=512 --rate=64k --name=null
--ioengine=null --size=512k --name=errorjob
--filename=/dev/mapper/errorend

errorjob: (g=0): rw=read, bs=(R) 512B-512B, (W) 512B-512B, (T)

But I can't tell if there's more to your issue because you didn't
include the exact job file/command line you were running with. Can you
update your fio to at least 3.0 (or git master), reproduce the problem
and include at least the information in
https://github.com/axboe/fio/blob/master/REPORTING-BUGS ? Thanks!
