If later verification jobs try to verify an area not written to, the header may not be there or/malformed thus generating error messages. -- Sitsofe | http://sucs.org/~sits/ On 22 July 2016 at 17:29, Saeed <ionictea@xxxxxxxxx> wrote: > Has anyone seen these errors before? > > Here's the job file: > > bs=4k > ioengine=libaio > iodepth=32 > size=1g > direct=1 > runtime=60 > filename=/dev/sdb > group_reporting > numjobs=10 > > # validation > do_verify=1 > verify_fatal=1 > verify_dump=1 > > verify_pattern=0x01020304 > > [mixed-a] > rw=readwrite > stonewall > > [mixed-b] > rw=randrw > stonewall > > [mixed-c] > rw=readwrite:4k > stonewall > > [mixed-d] > rw=randrw:4k > stonewall > > Errors: > > Multiple writers may overwrite blocks that belong to other jobs.
