Sure! dm-ioband is designed to be able to add new bandwidth control policies. dm-ioband-policy.c is a source code of "weight" and "weight-iosize" policies, and would help to understand how to add a new policy. > I don't know well about the details of dm-ioband controllers, concept, > design, architecture and so on. > it will take some time for me to do that ^^ > Well, Is there any documentations to help for me to understand the > existing implementation ? > If so, can I refer it ?

I have run dm-ioband on a logical volume disk and it worked well. http://people.valinux.co.jp/~ryov/dm-ioband/benchmark/lvm.html > > Oh, > Ryo tsuruta, sorry for many questions. > > Thank you > -- > Best Regards, > Dong-Jae Kang Thanks, Ryo Tsuruta _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
