Fair IO share between VZ containers?

[tmikaeld]

Hello,

How can i fairly split the IO resources between my four VZ containers?

One of them are using 70% of the whole servers IO resources, i wan't to correct that.

This is done by default using CFQ scheduler. But one container can still use 70% if others do not use the resources.

Thank you for the quick reply.

So if any of the other containers where to use more than 30%, the IO share would be lowered for the one consuming 70%?

If so, then all is well, we just don't want to get to the situation where one Virtual machine blocks all the others.

Yes.
