4. Stop the Grass Valley MetaDataService as follows:
• If a stand-alone K2 system, use the Services control panel to stop the service.
• If a K2 SAN, use Server Control Panel to stop the service on primary, and if present, backup
K2 Media Server with role of file system server.
5. Determine which backup file is the most recent good file by examining the file modification date
on each backup file.
6. Rename the current media.db file (which is assumed to be corrupt) to another name, and rename
the most recent good media.db_bakX file to media.db .
7. Restart the K2 system following normal procedures.
8. Confirm that the systems come up correctly with the restored database now in place.
9. Use Storage Utility
Clean Unreferenced Files
and
Clean Unreferenced Movies

inconsistencies between the contents of the database and the file system.
