Serial number for virtual pool 49/18/2023 ![]() ![]() This will act similar to an NAS server with mirrored RAID. This redundant GlusterFS cluster will consist of two Ubuntu 20.04 servers. This will provide functionality similar to a mirrored RAID configuration over the network: each independent server will contain its own copy of the data, allowing your applications to access either copy, thereby helping distribute your read load. In this guide, you will create a redundant clustered storage array, also known as a distributed file system or, as it’s referred to in the GlusterFS documentation, a Trusted Storage Pool. For instance, you can stripe data across different nodes in the cluster, or you can implement redundancy for better data availability. GlusterFS also gives you the freedom to create different kinds of storage configurations, many of which are functionally similar to RAID levels. In turn, this lets you treat multiple storage devices that are distributed among many computers as a single, more powerful unit. GlusterFS is a network-attached storage filesystem that allows you to pool storage resources of multiple machines. ![]() ![]() While many databases and other software allow you to spread data out in the context of a single application, other systems can operate on the filesystem level to ensure that data is copied to another location whenever it’s written to disk. When storing any critical data, having a single point of failure is very risky. An earlier version of this tutorial was written by Justin Ellingwood. ![]()
