OK, I know there are probably quite a few looking at this thinking…. “Hello where has he been?” when I’m talking about playing around with software raid under ubuntu linux, but…. in spite of all I’ve done supporting desktop systems and even small business servers I’ve never had an opportunity to setup a raid array. First it was because “you don’t want to do software raid” and I didn’t have a card to support hardware raid, then when I first was seeing people raving about how good linux software raid is, I didn’t have two free drives of equal size to work with. Well, the other day in working towards a storage system for a client I’ve got an ubuntu system (dapper 6.06.1) setup with software raid and wanted to poke and prod and test some things out before it goes into a useful role.

Software raid under linux (Ubuntu 6.06 Dapper Drake)
First, I should disclaim that this is going to be a brain dump of the resources and experience of a quick setup of Ubuntu 6.06 on a software raid based storage system. This may be less than ideal, but is doable and seems relatively solid as a system. First off, what is RAID (redundant array of independant/(*inexpensive) disks) So, several cheap hard drives put together in an “interesting” way. Now, increasing storage size isn’t something I’m too interested in, after all there are myriad other ways of expanding storage in a linux system (not to mention huge drives getting cheaper by the day.) My goal here is redundancy, I want to be able to lose a drive and still have the data, so RAID1 is what I’m setting up. We won’t get sidetracked into the other types.

Tools of the trade – USB2.0 to IDE & SATA Cable
Today is the first chance I”ve had to try out my new usb/ ide adapter “in the field”. I have previously used external ide enclosures for either laptop (2.5″) or desktop (3.5″) drives as well as larger (5.5″ cdrom’s) But, it was a bit of a nuisance to have to remove the drive that I had in the case and carrying around an empty case seemed like a waste, so I ordered this from Newegg.com It’s made by Sabrant (in China..) and is designed to connect any IDE or SATA drive to the usb port.

Developergo linux Livecd review
The thing I love about linux livecd’s is the ability to try before you make much of a commitment. You can boot, test, evaluate, and then reboot and be back at your usual desktop as if nothing has happened. (With emulators like QEMU and VMWare you don’t even have to reboot the PC.) There are a lot of Developer tools under linux, but until now I haven’t been aware of a distribution (livecd or otherwise) that is emphasizing those.
