GlusterFS is a distributed file system designed for scalability and high availability. It allows the creation of storage clusters across multiple servers, ensuring that data is replicated and accessible even during node failures. This capability makes GlusterFS suitable for high availability storage configurations where uptime and redundancy are critical.
High availability storage clusters can be built on common server hardware, providing cost-effective solutions for distributed data storage. GlusterFS can be configured on Linux distributions like Ubuntu, CentOS, and Red Hat. By connecting multiple nodes and managing storage volumes, GlusterFS offers flexible options to meet varying performance and storage requirements.
Using GlusterFS in a replicated mode ensures that data is available across multiple nodes, preventing data loss in case of hardware or system failure. For best results, it's recommended to use the XFS filesystem, though other filesystems may also be used. With GlusterFS, high availability storage clusters can be configured to handle large data volumes while ensuring data redundancy and fault tolerance.
Steps to set up a high availability storage cluster with GlusterFS:
- Install GlusterFS on each server in the cluster.
- Prepare a dedicated partition on each server for the GlusterFS volume.
XFS is the recommended filesystem for GlusterFS. Use it where possible.
Shared partition can also be used but is not recommended.
- Create a storage cluster by configuring peer nodes in the network.
- Create a GlusterFS volume using the prepared partitions.
