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.

Can corruption happen by powering off the computer (not properly shutting it down) during balance or scrub of a btrfs volume? (lemmy.ca)

Since btrfs uses Copy on Write, as long as the data makes it onto disk in tact, any further btrfs operations on the data will be safe against sudden power loss. It might need the opportunity to repair some stuff once power is restored (scrub), but the data (and metadata) should still be there and recoverable, not left in some partial state that can't be resolved.
