btrfs has eaten my data, which was probably my bad for trying out a newly stable filesystem around 15 years ago. there are plenty of bug reports of btrfs eating other people's data in the years since.

It's probably mostly stable now, but it's silly to act like it's a paragon of stability in the kernel.

And it's dishonest to act like bugs from 15 years ago justify present-tense claims that it is constantly eating people's data and is a bad joke. Nobody's arguing that btrfs doesn't have a past history of data loss, more than a decade ago; that's not what's being questioned here.

There's no need to call someone pointing out instability of a filesystem dishonest. That's bad faith.

I don't get why folks feel the need to come out and cheer for a tool like this, do you have skin in the game on whether or not btrfs is considered stable? Are you a contributor?

I don't get it.

But since you asked - let me find some recent bugs.

5.15.37 - fixes data corruption in database reads using btrfs https://www.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15....

5.15.65 - fixes double allocation and cache corruption https://www.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15....

6.1.105 - fixes O_APPEND with direct i/o can write corurpted files https://www.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.1...

6.1.110 - fixes fsync race and corruption https://www.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.1.1...

6.2.16 - fixes truncation of files causing data corruption https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.1...

btrfs-progs 6.2 fixes corruption on zstd extent read https://btrfs.readthedocs.io/en/latest/CHANGES.html

6.15.3, 4: possible data corruption, seems to be reparable: https://www.phoronix.com/news/Btrfs-Log-Tree-Corruption-Fix

Are people that encountered these also dishonest?
