Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10
Author: Falko Timme •
Tags: high-availability, storage, ubuntu •
Comments: 0 This tutorial shows how to combine four single storage servers (running Ubuntu 12.10) 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 12.10 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. 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.

Comments: 0 Running Contao 3.x On Nginx (LEMP) On Debian Wheezy/Ubuntu 12.10 This tutorial shows how you can install and run a Contao 3.x web site on a Debian Wheezy or Ubuntu 12.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10
Author: Falko Timme •
Tags: storage, ubuntu •
Comments: 1 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 12.10) with GlusterFS. The client system (Ubuntu 12.10 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. 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.

Automatic File Replication (Mirror) Across Two Storage Servers With GlusterFS 3.2.x On Ubuntu 12.10
Author: Falko Timme •
Tags: high-availability, storage, ubuntu •
Comments: 0 This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.10) 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 12.10 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. 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.

Comments: 0 How To Back Up MySQL Databases With mylvmbackup On Ubuntu 12.10 mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on an Ubuntu 12.10 server.

Creating An NFS-Like Standalone Storage Server With GlusterFS 3.2.x On Ubuntu 12.10
Author: Falko Timme •
Tags: storage, ubuntu •
Comments: 4 This tutorial shows how to set up a standalone storage server on Ubuntu 12.10. 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.

Tags: mysql, ubuntu •
Comments: 4 How To Install Percona Server 5.5 On Ubuntu 12.10 Percona Server is a drop-in replacement for MySQL. It offers more performance and scalability than the default MySQL server coming with your Linux distribution, while it uses the same init scripts and command line tools which makes it easy to use. This tutorial explains how to install Percona Server 5.5 on Ubuntu 12.10.

Using The btrfs Filesystem (With RAID1) With Ubuntu 12.10 On A Hetzner Server
Author: Falko Timme •
Tags: ubuntu •
Comments: 3 Using The btrfs Filesystem (With RAID1) With Ubuntu 12.10 On A Hetzner Server This tutorial shows how to install Ubuntu 12.10 on the btrfs filesystem (with RAID1) on a Hetzner server with two hard drives. While Hetzner's installimage tool doesn't list btrfs as a supported filesystem and only supports software RAID with /dev/md devices, it is still possible to achieve this setup and use the built-in RAID support in btrfs instead of using /dev/md devices.

VBoxHeadless - Running Virtual Machines With VirtualBox 4.2 On A Headless Ubuntu 12.10 Server

Comments: 3 VBoxHeadless - Running Virtual Machines With VirtualBox 4.2 On A Headless Ubuntu 12.10 Server This guide explains how you can run virtual machines with VirtualBox 4.2 on a headless Ubuntu 12.10 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

Using ATA Over Ethernet (AoE) On Ubuntu 12.10 (Initiator And Target)
Author: Falko Timme •
Tags: storage, ubuntu •
Comments: 1 This guide explains how you can set up an AoE target and an AoE initiator (client), both running Ubuntu 12.10. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.
