Striping Across Four Storage Nodes With GlusterFS On Mandriva 2010.0

Striping Across Four Storage Nodes With GlusterFS On Mandriva 2010.0

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 Mandriva 2010.0) with GlusterFS. The client system (Mandriva 2010.0 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.

High-Availability Storage With GlusterFS On Mandriva 2010.0 - Automatic File Replication Across Two Storage Servers

High-Availability Storage With GlusterFS On Mandriva 2010.0 - Automatic File Replication (Mirror) Across Two Storage Servers

This tutorial shows how to set up a high-availability storage with two storage servers (Mandriva 2010.0) 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 (Mandriva 2010.0 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.

Distributed Storage Across Four Storage Nodes With GlusterFS On Mandriva 2010.0

Distributed Storage Across Four Storage Nodes With GlusterFS On Mandriva 2010.0

This tutorial shows how to combine four single storage servers (running Mandriva 2010.0) to one large storage server (distributed storage) with GlusterFS. The client system (Mandriva 2010.0 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.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Mandriva 2010.0

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Mandriva 2010.0

This tutorial shows how to combine four single storage servers (running Mandriva 2010.0) 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 (Mandriva 2010.0 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 On Mandriva 2010.0

Creating An NFS-Like Standalone Storage Server With GlusterFS On Mandriva 2010.0

This tutorial shows how to set up a standalone storage server on Mandriva 2010.0. 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.

How To Set Up A USB-Over-IP Server And Client With Mandriva 2010.0

How To Set Up A USB-Over-IP Server And Client With Mandriva 2010.0

This tutorial shows how to set up a USB-over-IP server with Mandriva 2010.0 as well as a USB-over-IP client (also running Mandriva 2010.0). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices.

Server Monitoring With munin And monit On Mandriva 2010.0

Server Monitoring With munin And monit On Mandriva 2010.0

In this article I will describe how you can monitor your Mandriva 2010.0 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Mandriva 2010.0 Samba Standalone Server With tdbsam Backend

Mandriva 2010.0 Samba Standalone Server With tdbsam Backend

This tutorial explains the installation of a Samba fileserver on Mandriva 2010.0 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access.

Virtualization With KVM On A Mandriva 2010.0 Server

Virtualization With KVM On A Mandriva 2010.0 Server

This guide explains how you can install and use KVM for creating and running virtual machines on a Mandriva 2010.0 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

VBoxHeadless - Running Virtual Machines With VirtualBox 3.1.x On A Headless Mandriva 2010.0 Server

VBoxHeadless - Running Virtual Machines With VirtualBox 3.1.x On A Headless Mandriva 2010.0 Server

This guide explains how you can run virtual machines with Sun VirtualBox 3.1.x on a headless Mandriva 2010.0 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.
