Over the last few weeks, I've been playing with a foolish idea, mostly triggered by a cluster of people being confused by btrfs's free space reporting (df vs btrfs fi df vs btrfs fi show). I also wanted an excuse, and some code, to mess around in the depths of the FS data structures.Like all silly ideas, this one got a bit out of hand, and seems to have turned into something vaguely useful. I'm therefore pleased to announce the first major public release of btrfs-gui[1]: a point-and- click tool for managing btrfs filesystems.
This is a nice little tool. The one suggestion that I have is that it display the actual chunks and where they are located. It seems that right now it uses the same ioctl that btrfs fi df uses, and that just gets the total combined size for all chunks of a given type. It would be nice if the gui actually parsed the chunk tree and showed each individual chunk with lines showing how they are mapped to the physical disks.
