Linux operating system partition properties for QRadar installations on your own system
If you use your own appliance hardware, you can delete and re-create partitions on your Red Hat® Enterprise Linux® operating system rather than modify the default partitions.
Use the values in following table as a guide when you re-create the partitioning on your Red Hat Enterprise Linux operating system. You must use these partition names. Using other partition names can cause the installation to fail and other issues.
The file system for each partition is XFS.
