Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

This tutorial shows how to combine four single storage servers (running Ubuntu 12.04) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (Ubuntu 12.04 as well) will be able to access the storage as if it was a local filesystem.

High-Availability Storage With GlusterFS 3.2.x On Ubuntu 12.04 - Automatic File Replication Across Two Storage Servers

High-Availability Storage With GlusterFS 3.2.x On Ubuntu 12.04 - Automatic File Replication (Mirror) Across Two Storage Servers

This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.04) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 12.04 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Creating An NFS-Like Standalone Storage Server With GlusterFS 3.2.x On Ubuntu 12.04

Creating An NFS-Like Standalone Storage Server With GlusterFS 3.2.x On Ubuntu 12.04

This tutorial shows how to set up a standalone storage server on Ubuntu 12.04. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Your Cloud, Your Data, Your Way! - ownCloud 4.0 On CentOS 6.2 + nginx + PostgreSQL

Your Cloud, Your Data, Your Way! - ownCloud 4.0 On CentOS 6.2 + nginx + PostgreSQL

This document describes how to install and setup ownCloud by "ownCloud community" on a CentOS 6.2 based webserver from tar package on a nginx and php-fpm with postgreSQL database as backend. For other distributions there might be minor changes as to the software prerequisites installation procedures. This guide will not only help install the product, but also understand why certain points are done the way they are done (this is most helpful for users with little or no knowledge who, like me some time ago, have only started using Linux).

High-Availability Storage With GlusterFS 3.0.x On Debian Squeeze - Automatic File Replication Across Two Storage Servers

High-Availability Storage With GlusterFS 3.0.x On Debian Squeeze - Automatic File Replication (Mirror) Across Two Storage Servers

This tutorial shows how to set up a high-availability storage with two storage servers (Debian Squeeze) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Debian Squeeze as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes.

Encrypt Your Data With EncFS (Debian Squeeze/Ubuntu 11.10)

Encrypt Your Data With EncFS (Debian Squeeze/Ubuntu 11.10)

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. It is a pass-through filesystem, not an encrypted block device, which means it is created on top of an existing filesystem. This tutorial shows how you can use EncFS on Debian Squeeze/Ubuntu 11.10 to encrypt your data.

Proxmox VE 2.x With Software Raid

Proxmox VE 2.x With Software Raid

Proxmox Virtual Environment is an easy to use Open Source virtualization platform for running Virtual Appliances and Virtual Machines. Proxmox does not officially support software raid but I have found software raid to be very stable and in some cases have had better luck with it than hardware raid.

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 11.10

This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Ubuntu 11.10) with GlusterFS. The client system (Ubuntu 11.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes.
