The scenario is I have one master debian lenny running ispconfig3.3.3 hosting a couple of sites, emails, dns, and databases.
Slave a is in a datacentre and relies very little on the master other than to manage it and a coupe of DNS records.
Slave b is a mirror of Master with limited databases replicated (some of which are old) and using rsync to copy the contents of just the websites I believe.
Master has suffered a catastrophic failure and is at a remote location. I can't get it to boot. People who can see it tell me it reports a grub error 25. I won't be able to get to this Master until much later in the week.
Master and Slave B both sit behind a router which uses port forwarding to send all traffic to Master. The good news is, I've managed to now get the router to diver all traffic to Slave B.
Slave B is now serving up DNS records (which master previously did) and serve older versions of the websites... which is good for now.
So, my first task is I want to get Slave B to act as the Master now.
How do I do this?
The other good news that will hopefully assist with this is, I have been using go0ogl3's script to make backups of the master :
Master and Slave B do have different host names. Is this and issue? Their IP addresses shouldn't be an issue as they sat behind a router which would obviously be their public IP apparant to slave A.
The next task will be once I've looked at the problems on the failed Master, ie build a new one or permanently promote slave B to Master.
Your help is MUCH appreciated.
