Question & Answer
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.
