When it comes to file systems “pretty reliable” these days does not sound very good. Reliability had to have been a fundamental requirement for design of a file system. If not, it sounds like putting lipstick on a pig.

Redhat throwing towel on their support for development does not instill confidence either.

Nothing personally against Btrfs. Just an end user making a file system choice saying what I care about.

I have a laptop running opensuse, with root on btrfs. Twice I have had to reinstall because it managed to corrupt the file system.
