Frank, Sven, I totally agree with your thoughts on performing a proper benchmark study. The osd bench results we obtained when compared with Fio results didn't vary wildly and therefore the osd bench was adopted considering the minimal impact to the osd startup time. But this apparently is not always the case. In case the osd bench throws up unrealistic numbers, the recommendation would be to run a proper benchmark using reliable tools so that allocations for different types of operations are accurate and scheduling operations function correctly. In the immediate term we will improve the mclock documentation around this so that users are aware what to do in case they encounter such a situation. We will also explore options to determine IOPS capacity more reliably. Thank you for your feedback! -Sridhar _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
