Now I want a mirror of the other server.

I've set everything up, but nothing happens on the mirror.

You can only mirror settings of the services, data is not mirrored.

There are many option for data mirroring, e.g. rsync, a glusterfs share, a shared nfs server or a SAN. Personally I prefer to use glusterfs for that.

Mail data can appear to be mirrored... when you set up the mirror I believe it will create the mail user ids on the mirror, and although mails can be sent to that server and put in the new mail box, none of the old messages sent to the original server will be there.

I have used rsync to mirror the sites from the main to the slave:

My concern if I used a shared device for the data, then that would be the single point of failure.

Not if you ue e.g. glusterfs. Clusterfilesystems like glusterfs allow it to use a setup similar to raid over the network, where all files are stored on 2 or more servers incl. automatic repair of damaged shares. Glusterfs is better suited then rsync as it is near realtime. I would only use rsync when your server ar not connected to the internet with a fast connection e.g. if one server is in a datacenter and the other one hosted on a low mbit dsl line.

if you want to mirror a ispconfig server, then the slave has to run ispconfig of course, otherwise the configuration will not be mirrored. But this applies to all mirroring methods incl. rsync.

If you enter "glusterfs" in the howtoforge.com search field, you will find a lot of glusterfs tutorials.

or just normal


it's easy to do the installation.
