2021年11月15日 · sys.master_files is global, it contains a unified view of all databases' sys.database_files (more or less).

sys.master_files returns the "virtual" size of a file, while sys.dm_io_virtual_file_stats returns the on-disk size of the file. I only see different sizes for database snapshots, which use NTFS sparse files behind the scenes (and I did verify the allocated and on-disk sizes in Windows).

Now this would happen for every database so in sys.master_files I would see lots of different mdf names, but the same ldf name for every database.

2017年7月19日 · USE master; SELECT * FROM sys.master_files mf I understand looking at the Microsoft documentation that the sys.master_files view keeps track of files related to databases. On my system the 'type' column is only either 0 or 1 - i.e. I only have Log and Row files.
