I think it's good to get more data out there, positive and negative, so I'll add: I'm using btrfs on a home server (and sometimes desktop) for half a year now and haven't had any issues. It's fast (on nvme ssd), I can play with snapshots. It is admittedly a very lightly-loaded system. I filled up the root filesystem by accident once, which is supposed to be a very bad situation for btrfs. I was able to ssh in, diagnose stuff, delete the offending files, and then I did a minor rebalance to clean up some of the unnecessary metadata space that got allocated (not essential but I wanted to try it). No big deal and still works fine. I haven't used any btrfs raid features. I mirror it (via daily rsync) to an ext4 filesystem on another device to guard against filesystem-related bugs and device failure.
