I wish to god people would get a clue with BTRFS: - don't use it because you think the name is "cool". Every time I go to a linux meetup, some idiot starts talking about the name. - it takes 5-10 years for a filesystem or database to mature after it's released. Otherwise you will lose data and cry. - the recent BTRFS performance improvements are against itself, not other filesystems. EXT4 is an excellent fs, as good as XFS performance-wise overall.

  And it's been the default filesystem for openSUSE (system partitions only) since December 2015 [0], so there's been plenty of real-world usage too. [0] https://en.opensuse.org/Portal:13.2 https://en.opensuse.org/Portal:13.2

    Yeah, I remember that. I never do a separate home partition though, so I ended up with the entire disk in Btrfs. I wasn't paying as much attention as I should have when setting up partitions during installation, and didn't totally understand the implications of using Btrfs back then. Eventually though, it filled up my entire drive with snapshots, causing me much confusion and many disk full errors until I could figure out what had happened. That experience turned me off from openSUSE for several years, until I finally started using it (with a more conservative choice of Ext4) again for a few machines a couple years ago.

      The snapshots in this case come from suse, not btrfs itself. It's their package tooling creating them https://doc.opensuse.org/documentation/leap/reference/html/book.opensuse.reference/cha-snapper.html https://doc.opensuse.org/documentation/leap/reference/html/b... If you're on lvm, you're still getting snapshots now, even with ext4.

  Agreed, Btrfs has been out for quite a while. I think it is only now beginning to become more widely accepted or noticed by the broader community, which is both a blessing and curse. That said, I'm going to continue to opt for Ext4 or XFS for the time being, even on distros where Btrfs is the default. Probably in a few years I'll get around to upgrading to Btrfs.

    I use XFS too, but some large companies such as Facebook have adopted Btrfs on their servers. https://lwn.net/Articles/824855/ https://lwn.net/Articles/824855/
