I was thinking about alternatives to combine several HDDs together.
The only options I know so far are using LVM and/or RAID.
The thing is, using LVM, I will most probably lose all data, if one volume in my volume group fail. Using RAID, however, is (for my purposes) a waste of space.
So basically I am looking for a way to combine HDDs together, where I can remove and add more later on, but will not lose data from the other combined drive, if one disk fails.
I just heard about mhddfs. Is that a reliable method to combine disks?

Have you looked at ZFS?
It sounds like it would do exactly what you are looking for. And because, sometime a video is better than a wikipedia link: check-out this video
