[ceph-users] Re: Crush rule examples

How can I describe this in a crush rule?

Let me please add the point that causes me the most difficulties: I consider DC and host both to be failure domains. But still I accept that two copies go into one DC, but I don't want to accept that two copies go to one host. And also, how can I say "2 copies in DC1 and 2 copies in DC2", and not for example 3 copies in one DC, 1 copy in the other? -- Andre Tann
