    Hi ;
    I've never tried clustering, but I'm willing to.
    - are clustering installation still supported ?
    - install documentation about clustering are very old (debian 6 / 8), do you thing they are still valid for actuel distro ?
    - is it possible, on a basic installation (standalone web mysql email dns) to add a new server, which will be in a cluster (or mirror) with actual services ?
    Thanks.

    Yes.

    There is a Version for Ubuntu 20.04 and Debian 10. Should be the same process for Debian 11/12 / Ubuntu 22.04/24.04
    https://www.howtoforge.com/tutorial/ispconfig-multiserver-setup-debian-ubuntu/

    Not sure if it is possible to convert this into a multiserver setup. I would rather install a new multiserver setup and then use the migration toolkit to move the data to the new servers

    I created a new mailserver according to the perfect Multiserver guide,
    The new server shows up in ISPConfig, but in web, mail and rsync panels only the old servers are visible
    Any advise

    Mirrored servers shall not show up individually as they are mirrors, meaning they are mirroring their master.

    Still on the rsync issue, previous time i created a second mail server the error, user does not exits was solved by doing a rsync, this time I have the same issue the user does not exits on second server but I cannot use rsync as the second server is not availible due to being mirrored server even if i switch of mirroring?

    You must resync the primary server if its a mirrored setup as resyncing the primary server resyncs primary and mirror.

    Done the rsync but nothing chages, question I just stumbled on a chapter in the ISPConfig manual on replicating p 62 is this relevant for ISPconfig 3.2

    Is the new server you added listed under System > Server services in ISPConfig?
    If not, then your server is not connected to the master at all and needs to be reinstalled and connected at install time.
    If yes, have you selected it there to be a mirror of your mail server?
    If yes, then it will resync when you resync its master. You can use debug mode, enable it for the slave node, to see if it resyncs or not.
