I'm looking for a few suggestions on making a mirror machine: I had a video card fail on a machine yesterday. (I had a spare available.) The machine runs mail, web, webmail, imap, DNS, and ntp. Mostly a low traffic machine. I rsync backups to another machine (actually more than one) but I realized how much time it can take to get the machine up and running again.
So, I'm wondering about running a mirror that can be brought up in short notice. It's not "mission critical" so I'm not really interested in some kind of load-balancing/fail-over setup -- just a machine I can attach to the network and have it take over about where the last one was. What I currently have is one machine that is basically a mirror of another, but has different public and internal IPs. So to replace the main machine I'd have to go through the various configs and change IPs (and change bind from a slave to a master). Actually, it's currently a matter of changing a few symlinks, but still it's not a very good system. What I'd like to do, I think, is have a system that ran as a separate machine, but I could reboot and at the LILO prompt select another configuration that makes it boot with the other machines IPs and config settings. Perhaps mounting different /etc, /var, and /home. (and what else?) assuming I have the same package set and versions. Those /etc, /var, /home, etc. could be rsync backups based on this procedure: http://www.mikerubel.org/computers/rsync_snapshots/ Any Suggestions? -- Bill Moseley [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
