Well it's functionally broken, isn't it? A physical disk has a fixed IO bandwidth and when the administrator wants to partition that bandwidth amongst control groups he will need to consider the entire device when doing so? I mean, the whole point of this feature and of control groups as a whole is isolation. But /dev/sda1 and /dev/sda2 are very much _not_ isolated. Whereas /dev/sda and /dev/sdb are (to a large degree) isolated. _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
