🌐 Configuring GlusterFS - Marketplace

⚠️ All configurations shown in this manual are simple and hypothetical examples. Adaptations may be necessary depending on your environment's topology and structure.

This guide shows how to perform the installation and initial access to GlusterFS installed via the SaveinCloud Marketplace.

📌 What is the GlusterFS Replicated Volume?​

GlusterFS is an open-source distributed file system designed to provide scalable and high-performance storage.
A Replicated Volume in GlusterFS is a type of volume that maintains identical copies of data across multiple nodes (bricks), ensuring high availability and redundancy.

This means that whenever a file is written to the volume, it is automatically replicated on all configured nodes, preventing data loss in case of hardware failure or server unavailability.

Part 1 - Installing GlusterFS via Marketplace.​

With the SaveinCloud panel open, first, we will access the Marketplace tab.

With the Marketplace tab open, we will search for "GlusterFS" and proceed with the installation.

📌 What are Nodes in Cluster?​

In the installation of the GlusterFS Replicated Volume, the “Nodes in Cluster” option defines how many storage nodes (bricks) will compose the replication cluster.

Each node represents a storage server within the cluster. The configured value determines how many identical copies of the data will be maintained, ensuring redundancy and high availability.

🔑 How it works:​

  • 2 nodes → basic replication: if 1 node fails, data remains available.
  • 3 nodes → most common practice in critical environments, as it provides greater fault tolerance.
  • More than 3 nodes → increases resilience but also increases space consumption.

📌 Practical example:​

If the field is set to 3 (as in the image):

  • All data written to the volume will be replicated on 3 different nodes.
  • If up to 2 nodes fail, data remains accessible on the remaining node.

⚠️ Note:​

The final usable space of the volume equals the space of a single node, since all data is duplicated/reduced among the nodes.

  • Example: 3 nodes of 100 GB each → effective space = 100 GB (replicated 3x).

Confirm the installation and wait for it to complete.

After the installation is complete, access to the Storages can be done via WebSSH and configured according to the client's needs.
