Working with gmirror on a Sun Fire X2100

Post date: August 12, 2006, 18:08 Category: System Views: 3439 Comments
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.

Using Software RAID-1 with FreeBSD

Post date: November 29, 2005, 03:11 Category: System Views: 3629 Comments
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. 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.

Restoring a Sun system using JumpStart technology

Post date: April 13, 2005, 05:04 Category: Installing Views: 3918 Comments
Tutorial quote: If a server crash and the file systems are corrupted or totally destroyed, then the only way to recover the data is to restore from backups. If it is only user data that is corrupted, the task is in general simple, but if the system disk fails, then there is a little bit more work involved in order to to recover the system. This article explains how to backup Sun systems using ufsrestore over NFS, and how to use Sun's JumpStart technology to restore Sun servers and workstations over the network.

Connecting to a Wireless LAN with Linux, Part 2

Post date: April 13, 2005, 19:04 Category: Hardware Views: 3636 Comments
Tutorial quote: In Part 1 we reviewed hardware options, which wireless utilities should be present, how to use Windows drivers, and how to be open to connect to any available wireless access point. Today we'll cover configurations on Red Hat- and Debian-type systems, basic security, and hardware discovery.

Wireless connectivity can be rather overly friendly, allowing connections from anyone. This howto assumes you have a wireless access point on a LAN, which can be all wireless or mixed wired and wireless. You don't want it wide open to just any random person with a desire to snoop on your network or "borrow" your bandwidth, but you want some access controls and security. Your access point should have a unique SSID (service set identifier), WEP (wireless equivalent privacy) or WPA/WPA2 (Wi-fi protected access) set up and working, and either a DHCP server or a pool of assigned IP addresses for clients.

FreeBSD Networking Basics

Post date: April 13, 2005, 00:04 Category: Network Views: 3549 Comments
Tutorial quote: Beginners to Unix-like operating systems such as FreeBSD are often stymied by their network settings. Sure, the install process may have set up your NIC for you, but where do you go to view these settings, and how do you proceed if your NIC stops working? Since networking is such an integral part of computing, this article will demonstrate how to verify, configure, and optimize your network settings.
