Devices are the only real tangible thing that you can actually point at. They are the final physical unit and what gets added or replaced, and can be put in another machine for recovery. > What it really comes down to is how much space am I willing to > sacrifice so that my reliablilty is increasing. The answer as a whole is simple - you want all unused space for reliability and performance. If you put 5GB of data on 10GB of space then 50% is the value. > Rather than addressing that at a per-drive level with a futuristic fs > like btrfs I think setting a percent value of total space would be > best. The problem is that drives are what fail, can be added or removed. A percent value makes that considerably harder to deal with especially changes after the initial setup. It would be nice to be able to indicate that same data/files/directories are more important than others (eg cache/spool/trash directories are unimportant, my documents and photos are very important). > This is pretty much what it would be like in a perfect world, in my > opinion :) Conceptually I want to point at the drives and say "do the right thing" without any further configuration, monitoring or micro-managing. In the short/medium term I'd even be happy to run a btrfs cron job that digs around, rearranges things and gives me a final report with a colour coding homeland security style. When it hits yellow, it is time to delete files or add more storage.
