Hello, Please excuse this message if it is not appropriate... We run a small ISP with multiple FreeBSD servers providing all of our services. Four systems provide most of our essential services (such as DNS, Mail, and Radius authenticaiton). I'm wanting to come up with an effective way to 'mirror' drives across servers. The solution we should use, IMO, is RAID, but that's been shot down... so we're attempting to come up with an 'alternative'. Let's say we have servers A, B, C and D on the same ethernet segment like so: A---B---C---D What I would like to do is place spare drives in each server... So each system would have the drive(s) it needs for normal operation, plus a drive it isn't using... Then A and B could cross-mirror and C and D could do the same... So if any drive fails, I just hotswap from one server to the next (the idea being that if the mirror copy is across the network on another server, there's less chance of controller-related corruption - which happened to us once before). My question is, what's the best way to do something like this? I've thought about rdist, but have little-no experience in this area (I guess I'll have to become an rdist guru over the weekend - we all know the timeframes management gives us ;). What I'm basically hoping for is a brainstorming session... Either suggestions of something other than rdist to use (and hopefully some info about it) or effective ways to implement rdist. Thanks in advance, -mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
