As mentioned in my previous post I built myself a 2TB storage array.
Grabbed my old AMD 6000+ pc that was lying around, with 2GB of pretty sweet high speed RAM, threw in the spare 8600GT that was in the cupboard. For the drives I took 3 of the 750GB drives out of my desktop and bought two more.

So the box has 5 x 750gb drives in it configured in RAID 5. It gives me about 1.9TB after formating it to EXT3.
I had originally wanted to setup it up with XFS, but the original Fedora installation I tried failed miserably. Both Fedora 9 and 10 didn’t work all that well. Even tried Centos at one point, but got stuck with some hardware problems. Basically CentOS 5 doesn’t detect the Jmicron based SATA controller I put in it. Eventually went with Ubuntu 8.10. Decided to use ext3 as Ubuntu doesn’t seem to have great support for XFS. My main for trying the  XFS route, is it’s very easy to expand an XFS filesystem, if you make use of LVM. Far easier than EXT3. In the future i may want to increase the size of the array. EXT3 can be a pain in that regard, having had to expand a EXT3 2TB partition to 3TB before. I’ve also connected the VGA port to my HDTV, which I use as the screen. This lets me play movies off it, which is great.

So it doubles up as a very simple media pc and my storage system. It’s also shared via NFS and samba, so my windows and linux pc’s can access.

My reasoning behind it was, I was forever plagued with issues accessing my files. When I was in Ubuntu, if was a pain to access files under Windows and vice versa. But storing everything in one place and sharing it via Samba and NFS helps.
It also lets my brother dump any movies, series or games he has on there, so we keep what we have in sync.
Finally it makes a great backup. If I loose my drives, my brother has pretty much got everything I have and if his drives fail, he’s got it copied on my raid array. I’ve also found taking the extra drives out my desktop PC has helped reduce the heat and noise it was producing, which is great.

The only issue I’ve found with the storage array  is cooling. 5 drives tend to heat it up a bit. I’ve put a couple extra fans in to help. I’ve also enabled the CPU throttling on the box, so when it’s not busy it only runs at 1ghz. Saves electricity and pumps out less heat.
I think I need to get hold of a better case, as the one it is in at the moment is a bit small.

Thought it was a good project to post about though :)

Doing the storage shuffle…

At work I’ve been tasked with shuffling some of our storage around, cause it’s a bit of a rats nest at the moment.

I did all the prep work, was ready to go and unfortunately there were a large number of files deleted and added, so my top up rsync to backup the data will probably take 20 hours instead of 2 :(
Ah well. Epic Fail.
There is always next week.

Think I might bring my 2TB storage array from home in to help out with disk space :p

Sunfire gets my Vote

We took delivery of a brand spanking new Sun Sunfire x4150 at work recently. I’ve always had a soft spot for Sun. Having played around with some old SPARC servers a couple years ago, I find the Sun gear awesome to say the least.
I found the new Sunfire very sexy looking and the build quality is outstanding. The rail kit that came with the server makes what you get from Dell look like cheap crap. Completely tool free and no cage nuts in sight! A lot of thought has gone into the design. Amazingly enough, the Sunfire is actually assembled in the US. I like that.

So I installed CentOS 5.2 on this new shiny Sunfire and everything just worked out the box. Absolutely everything.
The box has 4 x 2.5″ SAS drives which were configured into a Raid 6 array. CentOS 5 was installed on top of that array. No issues.
The box itself is damn quick as well. Dual Quad Core Xeons help power this gear along.

Amazing thing is, I ordered a Dell XPS 1330 from dell.com.au and it took about 10 days to arrive. The Sunfire which came from the US, arrived in 3 days.
Makes you wonder. Sun can deliver a high end server from the US, faster than Dell and deliver a commodity laptop (worth about $3000 btw) from Malaysia.

Sun rocks!

Apple xRaid tools and nagios

No Gravatar

I found a good tool on nagios exchange today that can be used to monitor Apple xRaids (which appear to be extinct nowadays).
I specifically want to monitor for failed drives.

A very kind soul by the name of Steve from the University of Wisconsin wrote a nice package for monitoring xRaids.
Details here: http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F2624.html;d=1

I’m installing this package on Suse 10 Enterprise. When you run the configure for the xserve-raid-tools is doesn’t detect netcat even though the netcat package is installed.
I ended up running ln -s /usr/sbin/netcat /usr/sbin/nc
After that the configure finished successfully.

Has it been a month already?!

I haven’t posted anything for a while, which is bad of me, but time just flys.
My previous post was over a month ago…. whoops.

Last weekend I decided to go all out and buy a new Xbox360. I’d had a number of reservations regarding it, but now I have one, I realize just how well thought out and practical they are. As a PC gamer, I realize I spend far too much time fixing driver issues, unbreaking things and other general house keeping just to use my PC to play games or work. I’ve found that with the Xbox I can just throw a disk in and play. No pulling my hair out, or chasing down new Nvidia Drivers and oh is my DirectX up to date?!
I always maintained that a PC could pump out better graphics then the Xbox360, however I’ve had to eat those words. Gears of War 2 is just orgasmic in terms of HD Graphics. I’d have to spend a pretty fair whack of money to get my PC up to that level. Yes the Xbox rocks! I’m also a big fan of the Xbox Live Gold stuff.

My new job is going ok, however the guy that basically knows what is going has resigned and is off to Cyprus believe it or not. That leaves me the noob on my own to look after things. A daunting task, but I’m doing ok.

Other than that I’ve been applying for my permanent residence, which should hopefully happen soon. There was a news story about the Department of Immigration cutting the number of Visas they are dishing out by 17%. They have also changed the critical skills list, so electricians, boiler makers, plumbers etc aren’t in as much demand anymore. Seems like IT is still ok though. So we will see what happens.

A pretty scary story. About 2 weeks ago, the department my dad works for got a surprise.
There were about 80 people in the department and his employer retrenched all of the, except my dad and his boss…. eek. The other thing is they had just gotten another building to house the 80 people, but it basically only has two people in it.

The financial crisis is starting to hit pretty hard here in Australia. South Australia still seems ok, but there is definately a down turn happening. Wuite a few stores have closed down, not to mention many of the small cafes in the city. Ah well, what can you do.

I have to get back to work now, lol. Until the next post. Cheers.
