Looks like my article on right sizing RAID subsystems made it into the Feb 2011 Sys Admin issue of Linux Pro Magazine. Go grab a copy and flame me ;).
I know I have been pretty silent for a while, what can I say it has been busy. I did want to drop this little tip though. I use vim and gnome-terminal a LOT, so I hit ESC quite frequently. Being so close to the F1 key can be hazardous as I tend to mash the ESC key several times. I have no idea where I picked up the habbit of hitting ESC multiple times but its something I have done for a long time and I don’t see me retraining myself any time soon.
Singing with the stars is a reality show where the famous and not so famous SysAdmins strut their stuff and show off their skillz. Guest appearances by: Brian Atkisson, Brandi-Jvonne Mortimer, Matt Simmons, Joseph Kern, Ian Paredes, and Nick Anderson These are clips from the pilot show:

At $work we are in the process of migrating to Google Apps. Of course I am an early adopter to work out bugs and be a resource for others as they make the migration. One of the issues identified is mailto links pointing to google apps. Its not hard to make the change in firefox. First you need to set gecko.handlerService.allowRegisterFromDifferentHost to true in about:config (type about:config into your address bar).
When you get started as a SysAdmin you typically fall into one of 10 categories. You either had a mentor to show you the ropes, or you dredged through it on your on. It seems more and more the group that had or has a mentor is shrinking. I never had a mentor for the things I was most interested in, but my first boss did give good advice, and his words seem to ring in my head often.
Just a little tip, if your looking for bind stats and your chrooted rndc stats will give you rndc: 'stats' failed: permission denied All you have to do is touch /var/named/chroot/var/named/named.stats chown named:named /var/named/chroot/var/named/named.stats Now after you run rndc stats your named.stats fill will be populated with information.
Had a slightly vexing issue the other day. During a migration the destination host ended up caching some stale DNS entries. I tried a quick restart of nscd to no avail, rebooted the VM, again no joy. Even overriding the host in /etc/hosts wasn’t working. Took a few minutes of digging but what did work was nscd -i hosts . Just something to remember if you ever seem to have a stubborn caching issue, rebooting/restarting wont always solve the issue.
IMHO one of the great benefits of virtualization is the ability to properly size your guests. Many times 512M memory and an 8G / is plenty. Increasing memory for a virtual machine is typically pretty straight forward, but there are several options when adding disk space. Mounting the space in the file system and doing something with LVM are likely the most common paths. Depending on the situation I typically lean toward keeping my small 8G root and mounting extra storage where needed in the file system.
No one likes to forget to renew a domain. Its not wholly uncommon though. Microsoft forgot to renew passport.com in 1999, and hotmail.co.uk in 2003. Vivendi Universal forgot to renew its MP3.com in 2003, the Washington Post forgot to renew in 2004, and Foursquare forgot to renew their domain in 2010. I stumbled on the check_domain nagios plugin this weekend so I figured I would make some quick modifications and roll it into a Zenpack.
