The BTRFS filesystem has filled on the server, and thus some space needs to be freed up on it. There is a re-balancing feature available in btrfs. The primary purpose of the re-balance feature is to spread block groups across all devices so they match constraints defined by the respective profiles and this is done when btrfs need re-balancing to fix issues with chunks being un-balanced.
