Fixed In Version: Doc Type: Bug Fix
Doc Text:
The location of Pacemaker log files for RabbitMQ containers was not set to the correct location, which caused unnecessary log files to be created in /var/log/secure. This fix adds mounting of the /var/log/btmp path during the start of the RabbitMQ container, which enables Pacemaker to create the logs in the correct location.

Description Hervé Beraud 2018-10-24 15:02:29 UTC 
Description of problem:
Missing /var/log/btmp in rabbitmq container causes unnecessary logs in /var/log/secure.

~~~
su:pam_lastlog(su:session): unable to open /var/log/btmp: No such file or directory
~~~

The message is written in every su option for rabbitmq user.
It makes /var/log/secure larger and hard to read useful logs.

Version-Release number of selected component (if applicable):
Current openstack-triple-heat-templates.

How reproducible:
Always.

Steps to Reproduce:
1. Deploy RHOSP13
2. Login controller nodes.
3. Check /var/log/secure

Actual results:
The following log is written to /var/log/secure in every su for rabbitmq.
~~~
su:pam_lastlog(su:session): unable to open /var/log/btmp: No such file or directory
~~~

Expected results:
The log should not be written.

Additional info:
A simple solution for this is touch /var/log/btmp file in the container or create an empty file on the host directory, /var/log/pacemaker/bundles/rabbitmq-bundle-0
