Hi,dongsheng (and cc ceph-devel) I've updated my code with ceph master and compiled it, according to the description of pr ''rbd: implement image qos in tokenbucket algorithm", using the command "rbd image-meta set test conf_rbd_qos_iops_limit IOPS" could limit the R&W iops of rbd image. Then I use vstart.sh script to start my cluster, but using fio tool with rbd ioengine way to randwrite rbd image, there is no effect to limit IOPS with the above command, Is there something wrong with my operation or is there some other setting that must set?
Did you update your librbd.so with what you compiled? I think the reason is the fio is still using the old librbd you installed, rather than what you compiled. Yang
Any advice will be appreciated. Thank you! -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
