Heartbeat and ISpConfig 3 cluster

[till]

The above error is not related to creating a client in ispconfig. The query is from a ispconfig update were the ispconfig datannbase must have been updated or manually replaced before so that the updater could not recognize its structure due to a missing db version number in the server table of this server. So it is something related to your initial setup, maybe you installed ispconfig more then once on the server without removing it completely before.

You can e.g. try to skip this replication step in mysql.

Thank you for answer Till!

I reinstall ISPConfig and re-replicate mysql.

But question about mirroring, if I something create on slave server for expl. new mailbox. On should to be on master server too or mirroring goes only one direction?

I am asking because I create one email on slave and now did not see it on master. If it is normal it is ok.

But it is possible to create bi-direction mirroring?

Thank you.

The mirror guide installs a bidirectional mirroring. So it oes not matter if sou crate a mailbox on the master or the slave as the settings are applied on both servers automatically. At the end of the guide are instructions to copy the config.inc.php file from master to slave, this step is important ans has to be redone after an update to ensure that sou can use the ispconfig interface on the master and the slave.
