Problem

After the Update to 2.0, you may face this issue while trying to activate changes.


Also, you might encounter this error in conjunction:

Solution

Please check the web.log inside the Site directory (~/var/log/web.log). You will receive a message that the hard link cannot be created. 

/omd/sites/mysite/var/check_mk/site_configs/fe/local: b"cp: cannot create hard link 
'/omd/sites/mysite/var/check_mk/site_configs/fe/local/share/check_mk/agents/custom/my_mrpe_plugins/bin/check_http_ntlm' 
to '/omd/sites/mysite/local/share/check_mk/agents/custom/my_mrpe_plugins/bin/check_http_ntlm': Operation not permitted\n"


You might want to add the command to fix it:

root@linux:~# chown <sitename.> /PATH/of/the/hardlink

The Activate Changes should run now without problems.
