How To Set Up Software RAID1 On A Running System (Incl. GRUB Configuration) (CentOS 5.3)

How To Set Up Software RAID1 On A Running System (Incl. GRUB Configuration) (CentOS 5.3)

This guide explains how to set up software RAID1 on an already running CentOS 5.3 system. The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).

How To Set Up Software RAID1 On A Running LVM System (Incl. GRUB Configuration) (Debian Lenny)

How To Set Up Software RAID1 On A Running LVM System (Incl. GRUB Configuration) (Debian Lenny)

This guide explains how to set up software RAID1 on an already running LVM system (Debian Lenny). The GRUB bootloader will be configured in such a way that the system will still be able to boot if one of the hard drives fails (no matter which one).

Installing MySQL And phpMyAdmin On FreeNAS

Installing MySQL And phpMyAdmin On FreeNAS

This howto was written when I needed to run some php based web applications and the only system around was FreeNAS. Although many people are using php and MySQL on a FreeNAS box successfully I couldn't find any simple tutorial for the purpose, so I wrote one in case anyone needs it.

Ubuntu 9.04 Samba Server Integrated With Active Directory

Ubuntu 9.04 Samba Server Integrated With Active Directory

This howtos describes how an Ubuntu 9.04 Samba server is integrated with Active Directory, and how to use Winbind; the Linux server sees the domain users and groups transparently. I assume that your Ubuntu server is installed and ready to be configured with Samba.

Striping Across Four Storage Nodes With GlusterFS On Debian Lenny

Striping Across Four Storage Nodes With GlusterFS On Debian Lenny

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 Debian Lenny) with GlusterFS. The client system (Debian Lenny 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.

Using iSCSI On Ubuntu 9.04 (Initiator And Target)

Using iSCSI On Ubuntu 9.04 (Initiator And Target)

This guide explains how you can set up an iSCSI target and an iSCSI initiator (client), both running Ubuntu 9.04. The iSCSI protocol is a storage area network (SAN) protocol which allows iSCSI initiators to use storage devices on the (remote) iSCSI target using normal ethernet cabling. To the iSCSI initiator, the remote storage looks like a normal, locally-attached hard drive.

CentOS 5.3 Samba Standalone Server With tdbsam Backend

CentOS 5.3 Samba Standalone Server With tdbsam Backend

This tutorial explains the installation of a Samba fileserver on CentOS 5.3 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.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Debian Lenny

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Debian Lenny

This tutorial shows how to combine four single storage servers (running Debian Lenny) 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 (Debian Lenny 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 Portable DiskSafes With LoopbackFS And LVM Snapshots

Creating Portable DiskSafes With LoopbackFS And LVM Snapshots

This is the "DiskSafe" idea used to store backups of server data. This could be used to replace physical tape volume and still provide portablility. I have found pieces of this information around the Internet but nothing putting it all together.
