These options aren't needed, numjobs is 1 by default and RBD has no "sync"
concept at all. Operations are always "sync" by default.
In fact even --direct=1 may be redundant because there's no page cache
involved. However I keep it just in case - there is the RBD cache, what if
one day fio gets it enabled? :)
> how about adding: --sync=1 --numjobs=1 to the command as well?
With best regards,
