@mcc @whitequark i have a friend who despises btrfs and has had so many problems with it but i've been using it for years and it's always worked pretty well so idk? i think it can be a bit janky and confusing sometimes but imo a lot of that is just because it's so different from traditional filesystems
the one thing i can think of is that i've recently been getting some qgroup related warnings on my server that i'm not sure the cause of, i ran the command the message recommended to address the issue last night so we will see if it makes the messages go away
