Manually fixing bit flips in BTRFS

Somehow my BTRFS file system became corrupted by what appears to be a single bit flip in a metadata field. Rather than copying all the data and reformatting the file system, which would have required another disk at least as large as the original, I decided to try to fix this manually, which appears to have worked. I've documented the procedure I've used here, in case I need it again or someone else runs into a similar issue and finds it useful.

The first thing you should do is run btrfs check. For me this produced the following output:

Opening filesystem to check...
Checking filesystem on /dev/nvme0n1p1

# Sync two directories with rsync, but keep history to optimize the process.
# On subsequent runs it will only sync files added since last sync.
# This allows an easy continue in case script is interupted.
# This also helps with network connectivity to remotes since each file is 
# transfered by initiating new rsync command. This solves one issue I have
# faced when syncing large number of files and that is connection breaking
# if the process takes to long (in my case it was about 10hrs to transfer all
# the files).

12 Years of ToaruOS

This is a repost and update to an imgur album with screenshots of ToaruOS throughout its development, as imgur is no longer a viable platform for maintaining this collection.

Early Development

My first commit in the ToaruOS repository, ecd4fe2bc170b01ad700ff76c16da96993805355, was made on January 15th, 2011. This date has become ToaruOS's "birthday". It would be another six years and two weeks before ToaruOS's first real release, 1.0.
