Introduction to LVM in Linux

Date September 26, 2008

I’m going to go over the Logical Volume Manager (LVM) today, because it plays an important part in next Fridays’ howto. I’m not going to let the cat out of the bag, but just know that it’s been a long time coming. There are lots of resources for the technical management of LVMs, and they […]

Temporary Ignorance

Date September 25, 2008

It’s an interesting perspective, looking back and realizing how long you’ve spent to obtain the knowledge that you have.
