Can’t activate pending changes after copying a site

[marcohald]

CMK version:
2.1.0p9.cee
OS version:

Error message:
[Errno 13] Permission denied: '/omd/sites/Main/tmp/check_mk/data_source_cache/push-agent/mssql02'

This Error happens when I try to apply a change on a copied site.
The new site has the name serviceapi and is a copy of the site Main.
I already tried to “Remove TLS registration” on all hosts, but it had no effect.

The web.log contains these Lines.

I tried to find the source of the Path , when calling cmk.utils.paths.data_source_cache_dir from inside the site it looks alright

Hi,
do you have the file sites.mk in etc/check_mk/multisite.d? Is the original site in this file? If yes: Then replace Main with serviceapi.

Hi,

yes the file etc/check_mk/multisite.d/sites.mk exists. But the content does not contain Main

# Written by Checkmk store

sites.update({'serviceapi': {'alias': 'serviceapi', 'socket': ('local', None), 'proxy': None, 'timeout': 5, 'persist': False, 'url_prefix': '/serviceapi/', 'status_host': None, 'disabled': False, 'replication': None, 'multisiteurl': '', 'disable_wato': False, 'insecure': False, 'user_login': True, 'user_sync': 'all', 'replicate_ec': False, 'replicate_mkps': False, 'globals': {}}})

I found a fix for my Problem.
The Problem was that there were symbolic Links to the old site in the directory “/omd/sites/serviceapi/var/agent-receiver/received-outputs/”
What I don’t understand is that only 4 Links exist. in the Main Site there are over 70 Links.
So something must have been cleaned up automatically, but not all.
After the deletion I can apply changes without any errors.

@marcohald Great, we have the same problem but could not find a solution!
Found the symbolic links right there Thanks!
I am not very happy with the 2.1p at all…
