Tuning Up Your Linux Machines

Wednesday marked the beginning of the actual conference, as opposed to just the workshops and training sessions of the first few days. The attendance was much larger than earlier in the week, with people coming for the technical sessions and invited paper talks, and vendors have their booths set up to talk about their latest projects. As full as the schedule of the past few days have been, today it’s near the bursting point.

"Ahead in the Clouds" Lisa '09 Keynote by Werner Vogels

Werner Vogels, CTO of, was the keynote speaker at this year's LISA conference. His keynote was entitled "Ahead in the Clouds".

Eliminating Backup System Bottlenecks

I suspect that we all have a love/hate relationship with backups. Having backups done is a great feeling, but getting them to the point that you can absolutely count on them can be an exercise in frustration. Not only are they incredibly important, but the more you need them, the harder they are to do right.

"ZFS: A Filesystem for Modern Hardware" at LISA 2009

Richard Elling gave a tutorial on the ZFS filesystem. The tutorial included a complete overview of the filesystem from administrative commands to details of how the data is stored on disk.

The tutorial started off with a brief history of filesytems on Solaris and the design goals behind ZFS. This provided a good basis for the discussion of how ZFS was implemented.

IPv6 is the Future, and the Future is Now!

It’s Monday afternoon, and LISA is chugging right along! I’m well into my second day of training, and having a great time, and learning a ton that I’m going to take back to work.

Re-Enabling SELinux Training

This morning, I’m attending Rik Farrow’s “Working with SELinux” course. As soon as I walked into the room, it became apparent that I’m in the right place. On the screen was the lead slide of Rik’s show, and the title was “Re-enabling SELinux”. For me, that’s so appropriate, because one of the items on my “new machine” checklist is “disable SELinux”. To me, it’s always been a source of irritation that stopped me from performing actions necessary to administer the machine. The most frustrating part was always that I knew it didn’t have to be like that.
