QRadar: About /home partition

Question & Answer


What is the purpose of the /home partition in QRadar®, and how can I troubleshoot issues with the /home partition filling?


The /home partition is where user-specific configuration files for applications are stored.

By default, the QRadar disk sentry check runs every 60 seconds and looks for high disk usage across the /home partition. If the /home partition fills up, the QRadar disk sentry alerts but does not stop the QRadar core services, however it can create other symptoms such as configuration deployment changes due to critical disk space.

User leftover files are the most common cause of the /home partition filling up. Instead of /home, administrators can create a location for important data, such as /store/IBM_Support/, /store/save/, /store/important/, or /store/keep/ for exports, utilities, or important files.

Failed Update Error
When a software update runs, the /home partition is not checked to ensure the disk space has enough space for the update. However, it is advised remediating any disk space issues before the update runs as suggested in the QRadar: Software update checklist for administrators.
Troubleshooting Disk Space Issues
To determine which files or directories are filling the /home partition and how to release space safely, follow the steps in the following articles:
