Hi! This could be quite difficult to keep "distances" in IP addresses. We introduced rack maps which should be easier in the mainenance. It would be soon available in the public version.

Subject: [Moosefs-users] geographical fun with MooseFS What if someone wrote a patch for MooseFS that looked at the IP of the client, and the IP of the chunk servers that had the chunk the client wanted, and tried to pick the closest one? something like client = 10.1.1.1 chunkserver with copy#1 = 10.1.1.2 chunkserver with copy#2 = 10.1.1.20 chunkserver with copy#3 = 10.1.2.2 Those 3 chunk servers would be used in that order, since their IPs are closer to the client's IP (using a formula like a*256^3+b*256^2+c*256+d to calculate an integer? long int? based on an IP address). This way you could have "close" chunk servers respond to most of the requests from a client, but if no "close" server had the chunk you wanted, you could go to a "distant" one. Drop two IPs on the client's interface, and do some careful numbering, and you can even set preference on a machine on the same LAN. This might make for a really simple way to do "distant" archives that don't get used for reads unless they are the only source that's available, and other similar problems. writes would be a different problem.
