Random overwrite and verify workload

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I am interested in generating a workload consisting of mixed-length random overwrites followed by final verification, i.e.:

rw=randwrite
norandommap=1
bsrange=1k:4k
blockalign=512
verify=meta
do_verify=1
...

Of course, verification is incompatible with norandommap when used with multiple blocksizes, so this won't work currently.

Is such a feature on the fio roadmap?

Would a patch implementing such a feature be considered?

Thanks,
Justin
