Hello, I have 3 hard drive with 750 GB, 500 GB and 250 GB. I want to use btrfs as filesystem. This will be my first test installation of btrfs. My target is to get redundancy as well as a 750 GB data capacity. So I was thinking to create a raid0 with the 500 and 250 GB drive. This would result in a raid0 with 750 GB capacity. I want to add this raid0 as a mirror in a raid1 with the other 750 GB drive. But how do I do that? Thanks Matthias
