I am a neatfreak. Not in real life but on my computer. Everything must be in the right folder with the right name. I don’t like clutter on my desktop. I hate it. But i have a reasonably large video and music collection. But it’s difficult to keep it neat with three seperate hard drives. I used to have a /data folder with in that folder 3 different folders linked to the different disks. I had one disks for Animé and Music, one disk for TV-shows and one for Movies. But I don’t have that much Anime and Music so I have a lot of unused space on that disk. But I can’t put other stuff on there and still keep it organised. I was interested in raid but raid 1 is a waste of space, raid 5 is nice but for good performance you need a raid card, and raid 0 is too insecure.
And then I discoverd Lvm. Lvm stands for Logical Volume Manager. What it does is it combines hard drives and partitions (physical volumes) into a large volume group. Within this volume group you can make partitions that cover multiple hard drives.
So what I did was combine all my drives into one large 2.16 TB partition. And I love it. If your interested as well, use this howto. It’s all you need. And this is what I love about linux. I like to finetune my system. And this was so much easier than I thought but remember, ALWAYS BACKUP YOUR DATA.
