Inter-Server Synchronization version 2

If you have more than one SUSE Multi-Linux Manager installation, you will need to copy contents between servers. Inter-Server Synchronization (ISS) allows you to export data from one server (hub) and import it on another server (peripheral). This is useful for hub deployment scenarios or disconnected setups.

1. Install Inter-Server Synchronization packages

To use ISS you need to install the inter-server-sync package on hub and peripheral servers.

2. Content synchronization

Use mgrctl term before running steps inside the server container.

Procedure: Export data on hub server
  1. On the hub server, on the command line execute the ISS export command. The -h option provides detailed help:

    inter-server-sync export -h

The export procedure creates an output directory with all the needed data for the import procedure.

Procedure: Copy export directory to peripheral server
  1. Contents from the hub server needs to be synchronized to the peripheral server. On the command line, as root, execute:

    rsync -r <PATH_EXPORTED_DIR> root@<TARGET_SERVER>:~/

When all contents is copied, start importing it.

Procedure: Import data on peripheral server
  1. On the peripheral server, on the command line execute the ISS import command. The -h option provides detailed help:

    inter-server-sync import -h

3. Database connection configuration

Database connection configuration is loaded by default from /etc/rhn/rhn.conf. Properties file location can be overridden with parameter --serverConfig.

4. Known limitations

  • Hub and peripheral servers need to be on the same version.

  • Export and import organization should have exactly the same name. The organization name is case sensitive.
