An important part of maintaining the performance of a Red Hat Enterprise Linux 6 system involves ensuring that adequate swap space is available comparable to memory demands placed on the system. The goal of this chapter, therefore, is to provide an overview of swap management on RHEL 6.
By default, RHEL 6 configures swap space using Logical Volume Management (LVM). An alternative to adding swap via file, therefore, is to extend the logical volume used for the swap.
