…olume_stats Adds volume_mount_point, volume_total_mb, volume_free_mb to the database_size_stats collector so every file row carries its drive context. On-prem uses CROSS APPLY sys.dm_os_volume_stats(); Azure SQL DB gets NULLs (DMV not available). Tested on sql2022: 39 rows, all with C:\ volume data (409 GB total, 135 GB free).
