Using Software RAID-1 with FreeBSD

Post date: April 28, 2008, 17:04 Category: System Views: 6035 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.

Using Software RAID-1 with FreeBSD

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.

Monitoring and Managing Linux Software RAID

Post date: April 15, 2005, 23:04 Category: System Views: 2757 Comments
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.

Network-Attached Storage With FreeNAS

Post date: February 13, 2007, 19:02 Category: Installing Views: 8840 Comments
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.

Debian RAID 1/5 system installer

Post date: May 28, 2005, 22:05 Category: Installing Views: 3126 Comments
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.

Secure Batch Email on FreeBSD with UUCP and SSH

Post date: April 19, 2005, 02:04 Category: Network Views: 3061 Comments
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.
