You are managing a Red Hat Enterprise Linux 9 server that hosts a critical database application. The database stores its data on an XFS filesystem mounted on /data, backed by a logical volume in a volume group named vg_db. Recently, the database team reported that write operations are failing with 'Disk quota exceeded' errors, but the filesystem still shows 40% free space.
