Working with gmirror on a Sun Fire X2100

Post date: August 12, 2006, 18:08 Category: System Views: 3483 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: 3678 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: 3991 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.

Working with SUSE Linux Enterprise Server 9

Post date: June 22, 2005, 09:06 Category: System Views: 3482 Comments
Tutorial quote: Working with SUSE Linux Enterprise Server (SLES) requires an understanding of the login process, including local account files, system accounts, and managing identities.

Using a console shell or the graphical environment are two possible methods of working on a SLES machine.

Finding your way around a SLES installation requires an in-depth knowledge of the filesystem layout. Essential filesystem components are documented and explained in this chapter. Basic filesystem permissions are also described.

Tutorial quote: When I made the switch to Ubuntu Linux on my desktop computer (that is, if you can call triple-booting Windows XP, Vista, and Ubuntu a "switch"), I was a little worried about finding the applications and tools that would make me as productive working in Ubuntu as I am working on Windows.
