How to extend Swap Space in Logical Volume on RedHat 7
Extend Swap Space in Logical Volume on RHEL 7/CentOS 7/RHEL 8/CentOS 8 In this lab, we will learn how to increase swap space on RHEL 7/CentOS 7/RHEL 8/CentOS 8 Linux base operating system. The purpose to use swap space is when ram of the operating system fully utilize, swap space allocate from the hard drive of the machine and take inactive pages available in memory. One important point to remember memory is a combination of RAM and SWAP and memory is utilize by the each process of CPU (Central processing unit). If swap is use rather than ram (random access memory), system performance will slow. You can say swap space is a part of virtual memory (disk space and ram) or sub title of physical memory. Definition of Swap Space: The definition of swap space is exchange the information means swapping information from real memory to virtual memory by use of disk space that is called swap space. Advantage of Swap Space: Sometime swap space require when application or program is creatin...
