I'm coming to Linux from a platform where incorporating additional storage could be as simple as plugging in the drive and configuring it in online as part of any volume set.
Things don't seem as easy on Linux. I have a RH 7.3 system that was created with one disk drive. I've added a second, creating a single partition and formatting it as EXT3 (same as first drive). What I want to be able to do is have /usr, /var, etc. be able to use the space on the new drive. In my words, incorporate the added drive in the / volume space. This does not seem possible - or am I missing something?
