FreeBSD Using Software RAID-1 with FreeBSD
Post date: April 28, 2008, 17:04 Category: System Views: 2286 Comments: 0
Tutorial quote: Have you ever needed a software RAID solution for a low-end server install? Perhaps you've wanted your workstation to take advantage of the redundancy provided by a disk mirror without investing in a hardware RAID controller. Has a prior painful configuration experience turned you off software RAID altogether on Unix systems?

Since 5.3-Release, FreeBSD comes with gmirror(8), which allows you to easily configure a software RAID 1 solution.

Since 5.3-Release, FreeBSD comes with gmirror(8), which allows you to easily configure a software RAID 1 solution. While tutorials on gmirror exist, I found them to require either manual calculations of partition sizes with bsdlabel or the use of a fix-it floppy on an existing system.

It made more sense to me to configure RAID during the install of the operating system. I also wanted a procedure that was easy to follow and didn't introduce human error in the form of a math miscalculation. After cobbling together the available documentation and experimenting my way through various configurations, I came across a procedure that has worked well for me on several different systems. I also received valuable feedback from Pawel Jakub Dawidek, the author of gmirror, who gave some insight into some of the not yet documented features of gmirror.
Linux Monitoring and Managing Linux Software RAID
Post date: April 15, 2005, 23:04 Category: System Views: 1205 Comments: 0
Tutorial quote: Systems administrators managing a data center face numerous challenges to achieve required availability and uptime. Two of the main challenges are shrinking budgets (for hardware, software, and staffing) and short deadlines in which to deliver solutions. The Linux community has developed kernel support for software RAID (Redundant Array of Inexpensive Disks) to help meet those challenges. Software RAID, properly implemented, can eliminate system downtime caused by disk drive errors. The source code to the Linux kernel, the RAID modules, and the raidtools package are available at minimal cost under the GNU Public License. The interface is well documented and comprehensible to a moderately experienced Linux systems administrator.

In this article, I'll provide an overview of the software RAID implementation in the Linux 2.4.X kernel. I will describe the creation and activation of software RAID devices as well as the management of active RAID devices. Finally, I will discuss some procedures for recovering from a failed disk unit.
Gentoo RAID over NFS
Post date: June 17, 2005, 11:06 Category: Network Views: 1701 Comments: 0
Tutorial quote: This is a HowTo to create a RAID over NFS. In this case RAID5, but can be easily adopted for other RAID levels.
BSD Network-Attached Storage With FreeNAS
Post date: February 13, 2007, 19:02 Category: Installing Views: 3794 Comments: 1
Tutorial quote: This tutorial shows how you can set up a network-attached storage server with FreeNAS. FreeNAS is based on the FreeBSD operating system and supports CIFS (samba), FTP, NFS, RSYNC, SSH, local user authentication, and software RAID (0, 1, 5). It comes with a powerful web interface and uses very little space on the hard drive - about 32MB.
OpenBSD OpenBSD encrypted raid disk

Debian Debian RAID 1/5 system installer
Post date: May 28, 2005, 22:05 Category: Installing Views: 1585 Comments: 0
Tutorial quote: Instructions for installing a very clean Debian GNU/Linux system that boots from RAID 1, and has RAID 1 or RAID 5 root and data filesystems.

The examples assume two identical harddrives, sda and sdb, on which after a small boot partition, 1 GB is used for swap, 25 GB is used for the root filesystem and everything else is for a big "data" partition that will hold non-system stuff.
FreeBSD Secure Batch Email on FreeBSD with UUCP and SSH
Post date: April 19, 2005, 02:04 Category: Network Views: 1149 Comments: 0
Tutorial quote: Not everyone has reliable, always-on Internet access. For some, reliability has to come through software, not hardware. Fortunately, protocols designed to work around slow and unreliable networks still work. Christophe Prevotaux demonstrates how to set up FreeBSD, Postfix, and SSH to send and receive email via UUCP.
FreeBSD Working with gmirror on a Sun Fire X2100
Post date: August 12, 2006, 18:08 Category: System Views: 1546 Comments: 0
Tutorial quote: Mirror setup. Recently I was given a brand new X2100 server made by Sun Microsystems. I installed FreeBSD on it and run a mailserver. The server has two 250GB SATA drives and I decided to use gmirror(8) to create RAID-1 on those disks.
FreeBSD Setting up Linux compatibility on FreeBSD 6
Post date: April 3, 2006, 06:04 Category: System Views: 1569 Comments: 0
Tutorial quote: As a FreeBSD desktop user I occasionally feel left out when it comes to the availability of applications, particularly desktop applications or binary-only browser plugins produced by commercial closed source vendors. Sometimes a good alternative lurks in the vast FreeBSD ports collection, but not always. The version available may lag a couple of revisions behind what I need, or the port might exclude my particular architecture. Fortunately, FreeBSD can run binaries and shared libraries that have been compiled for Linux and other Unix ABIs (such as SVR4 and SCO).

In this article I will cover the steps necessary to enable and configure Linux binary compatibility on FreeBSD 6. I'll also share a couple of my own experiences with getting some well-known desktop Linux applications to run on FreeBSD 6.
