From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Probably depends a lot on what options you had enabled on BTRFS. Metadata (i.e. what files are stored where) is normally replicated so you may be able to rebuild the information.
Step 1 is always to copy the filesystem somewhere else, and then work on the copy. That way, if you screw up, you can always make a new copy and start over. Don't write anything to the drive you're trying to fix. Always work on the copy. In fact, once you've made the copy, disconnect the original.
