I've been Linux user for over 10 years, and been computing since around age 11. I got my start in programming by learning Perl on my Debian machine in high school. Since then I've learned numerous languages including C, C++, and Python. I've also dabbled in Java and assembly.

I have a bachelors degree in Computer Engineering from Simon Fraser University in Burnaby, BC, Canada.

I've worked in Japan as a CAD software developer in C++ on Windows. Not my favorite environment, but an interesting project never the less.

I'm currently employed by a Vancouver-based biotech startup working primarily on systems level projects but doing my fair share of software development.

My favorite programming language is Python and I use it nearly every day. My recent interests lie in virtualization, hpc, and large-scale systems management. I'm an active contributor to the Bcfg2 project.

comment How to tell what process has a specific port open on Linux?
If neither netstat nor lsof show the port as being used, but the machine is responding to it, chances are there's been a root kit installed. I recommend moving any data off the machine somewhere else and then nuking it.

comment Open Directory Failover
Yes, I've read that. It's also possible that the second scenario they are describing is more appropriate for a remote site that replicates from a master site somewhere. The clients would then be configured authenticate with the replica by default simply because of proximity reasons.

Thanks. This really seems like the crux of the problem. We'll look at ways to rectify it.

comment Linux server is only using 60% of memory, then swapping
I'll look at some of your suggestions. No, I'm not crazy and running a production database on the backup system. The PostgreSQL is part of the backup system, as Bacula uses that as its information store for keeping track of what is on what tape, etc. I'll take a look at tuning some of the parameters you specified. The high I/O throughput is a result of other servers dumping data to this server's disk tray, and this server subsequently pulling that data and writing it to an LTO4 tape library.

comment What's a good tool for collecting statistics on filesystem usage?
I think Evan pretty much hit the nail on the head with the link to that paper. That's basically the exact kind of data I'd like to be able to collect. Just trying to see if there's a way short of purchasing an expensive NetApp box to do it :)

It's an SGI Altix XE240, I'm pretty sure it can support more than 4 GB of RAM as I've used demo units with 32 GB.

comment What's a good tool for collecting statistics on filesystem usage?
The operating system is Linux. Sure, I can do ls, but I don't see how running that on a 12TB filesystem is going to give me a concise view of its usage characteristics without me writing a lot of code to analyze the output from multiple runs.

comment Extending the Filesystem Hierarchy Standard (FHS) to house Enterprise Software
I also think this is pretty much the best way to go. It also doesn't require any "extension" to the FHS. Isn't this already the standard?

comment How to manage Xen virtual machines on shared SAN storage?
Perfect! That's exactly what I was looking for. The xend-domain-lock-utility could presumably even hook in to a clustered volume manager or something similar. I've accepted the answer, but maybe you can update it with the specific configuration bits out of the comments just to make it a bit more clear?
