Combine your partition space with mhddfs.
As I was browsing the Gentoo forums today, I came across a very interesting post. A user had 2 partitions on different hard drives that he wanted to combine the space on. Ok, well the interesting part was one persons reply about a new fuse filesystem called mhddfs. He pointed out an article on debian.net that explained a bit about this new filesystem and how to use it. Sure, there’s multiple ways to combine the two drives, but this one is pretty intesting.
