Environment:

fio version: fio-3.29

Reproduction steps
use two clients
A client writes files to 4M,
B client runcate to 512k
A client read files with verify

config:
[global]
verify=md5
rw=read
name=test
create_on_open=1
nrfiles=1
numjobs=100
do_verify=0
group_reporting
directory=/opt/testTools/TcBetaSfsLongDataMixoperation003
ioengine=libaio
bsrange=1k-256k
iodepth=32
size=100%
[repeat_write]
