Identifying a corrupt media database
1. Check the following symptoms, as they could indicate a corrupt media database:
• On startup, the Grass Valley MetaDataService is unable to start. This is indicated in the
Services control panel if the Grass Valley MetaDataService does not display as Started.
• The K2 log displays a “…file is encrypted or is not a database…” error.
2. As soon as you suspect a corrupt media database, stop all media access and take the K2 system
offline.
Restoring the media database
1. Stop all media access and take the K2 system offline.
If a K2 SAN, follow procedures to take connected K2 client systems and K2 Media Servers
offline. Shutdown connected K2 client systems. Refer to the K2 SAN Installation and Service
Manual.
2. Navigate to the V:\media directory.
If a K2 SAN, access this directory from a K2 Media Server with role of media file system server.
3. Make a copy of the media.db and media.db_bak* files and store them in a secure location.
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
to repair any
inconsistencies between the contents of the database and the file system.
