We will learn how to install it on CentOS 7.9 in this post. ZFS is not included by default in CentOS. All processes on the system automatically use the additional memory.

In many ways, the storage pool works similarly to a virtual memory system: When a memory DIMM is added to a system, the operating system doesn’t force you to run commands to configure the memory and assign it to individual processes. When new storage is added, all file systems within the pool can immediately use the additional disk space without additional work. You no longer need to predetermine the size of a file system, as file systems grow automatically within the disk space allocated to the storage pool. File systems are no longer constrained to individual devices, allowing them to share disk space with all file systems in the pool. The storage pool describes the physical characteristics of the storage (device layout, data redundancy, and so on) and acts as an arbitrary data store from which file systems can be created. Instead of forcing you to create virtualized volumes, ZFS aggregates devices into a storage pool. ZFS eliminates volume management altogether. This design added another layer of complexity and ultimately prevented certain file system advances because the file system had no control over the physical placement of data on the virtualized volumes.

To address multiple devices and provide for data redundancy, the concept of a volume manager was introduced to provide a representation of a single device so that file systems would not need to be modified to take advantage of multiple devices. Historically, file systems were constructed on top of a single physical device. ZFS uses the concept of storage pools to manage physical storage. ZFS is robust, scalable, and easy to administer. The ZFS file system is a revolutionary new file system that fundamentally changes the way file systems are administered, with features and benefits not found in any other file system available today. Source1 Source2 ZFS and ZFS Pooled Storage OpenZFS is an outstanding storage platform that encompasses the functionality of traditional filesystems, volume managers, and more, with consistent reliability, functionality and performance across all distributions. The OpenZFS project is an open source derivative of the Oracle ZFS project.
