The structure of the output from ‘btrfs filesystem df’ is different from the output of the commend ‘df -h’.

Is there an advise how to read it?

What is the critical value?

Hi and welcome to the Forum 😄

`btrfs fi usage /` will provide more information on overall use. The `man 8 btrfs-filesystem` command will provide more information on Data, System, Metadata and GlobalReserve.
