Using rsnapshot to back up and retain snapshots

Vincent Danen    //    Wed 21 April 2010    //    Linux    //    techmail backup

Last week's techmail was Using rsnapshot to back up and retain snapshots. Rsnapshot is pretty slick; the tip goes into the how and the why, but now that I've found this thing I think it's going to replace my home-brew rsync backup solution. I use subversion to retain old backups …

runit and supervised services on RHEL/CentOS 5

Vincent Danen    //    Wed 07 April 2010    //    Linux    //    rhel

I'm sure I've mentioned this before, but I maintain a repository of packages for Red Hat Enterprise Linux 5 (arguably these could/should be in EPEL but I've not had time to get into the Fedora side of things as of yet... someone will beat me with a wet noodle …

Using smartctl to get SMART status information on your hard drives

Vincent Danen    //    Thu 01 April 2010    //    Linux    //    techmail

This week's techmail is Using smartctl to get SMART status information on your hard drives. Smartctl is awesome, and having it monitor your drives on a constant basis will likely give you the early warning "oh crap, something is wrong, backup NOW!" that people can really use. I know it's …

Replace a failed drive in Linux RAID

Vincent Danen    //    Tue 23 March 2010    //    Linux    //    techmail raid

This week's TechMail is Replace a failed drive in Linux RAID which goes into the fun I had on a Sunday afternoon a few weeks ago replacing a drive in my backup box at my mother's place. All-in-all it was dead simple and very painless, which just goes to show …

Enhanced history searching in zsh

Vincent Danen    //    Sat 20 March 2010    //    Linux    //    techmail shell

This week's TechMail is Enhanced history searching in zsh because I seem to always be doing the same thing over and over again and it's good to save keystrokes. =) I imagine other people are in the same boat as well, so there you go... something simple yet useful.

Introducing Linux virtual containers with LXC

Vincent Danen    //    Sat 27 February 2010    //    Linux    //    techmail containers

This week's techmail is Introducing Linux virtual containers with LXC. I played with LXC for the first time a little while ago when writing this tip, and it's pretty slick. It's not quite as feature-complete or as robust as OpenVZ, but it's very close. It also has some benefits over …
