After copying or moving a site with omd mv or omd cp, Checkmk will show you duplicate hosts and services.

This is a known issue which needs a bigger rewrite of our code an it will take a while.


To avoid the issue, you might want to modify the following .mk files

  • ~/etc/check_mk/multisite.d/
  • ~/etc/check_mk/
  • ~/etc/check_mk/conf.d/
  • ~/etc/nagvis/conf.d/cmk_backends.ini.php
  • ~/etc/nagvis/maps/<mapname>.cfg
  • ~/etc/nagvis/*
  • ~/local

In case you're using the dcd you need to modify the dcd connection and recreate the hosts.

In big environments, you could modify the following files:




Please be careful with modifying these files. We dont't support any modification. We would recommend modifying the hosts via WATO/SETUP or remove and recreate the hosts via the DCD.

Issue with Agent Bakery

ValueError ('/omd/sites/cme2/share/check_mk/agents/check_mk_agent.aix' does not start with '/omd/sites/bak/share/check_mk/agents')


Every time the bakery is running, we create a status file. After copying or moving the site you need to delete this file.
