Hi,
I am trying data integration cases with verify_pattern option.
I am not seeing any dump file generated for the mismatch.
Here are the steps i followed,
Started fio and waited till 30 % writes done the disk and issued a dd
write on the same disc for the first 512 bytes with pattern zero.
then waited till verify gets completed.
I can see the error's in the output log file but not the dump file.
Here is my job file.
[global]
size=10g
direct=1
filename=/dev/sdc
verify_pattern=0x01010101
verify=meta
bs=64k
group_reporting
[write-phase]
rw=write
do_verify=0
[verify-phase]
stonewall
rw=read
do_verify=1
continue_on_error=all
verify_dump=1
~
Let me know if i am missing something over here.
Here is my log file for the verify part,

2)Also i have one query like verify_pattern option is it possible to
provide known pattern for write and reads this will be very useful in
DI verification test cases
Thanks,
