Checking the media file system
Prerequisites are as follows:
• You must access Storage Utility (via the K2Config application login) with permissions equivalent
to K2 administrator or higher.
• When you access Storage Utility, the K2 SAN must be offline.
• All iSCSI clients and K2 clients in the K2 SAN must be offline.
• K2 Media Servers with role of file system/metadata server, both primary and redundant, must
be powered up but offline.
This procedure checks the media file system but retains current media files.
NOTE: This procedure can take 20 hours or more on a large SAN. Do not start this process
unless you have adequate time set aside.
1. In Storage Utility, click Tools | Check File System .
2. A message box appears “Checking media file system. Please wait”. Observe progress.
If problems are discovered they are reported. If the check process passes, when the process is
complete a message appears to confirm success.
3. Click OK to dismiss the results.
Your file system has been checked.
Cleaning unreferenced files and movies

• All iSCSI clients and K2 clients in the K2 SAN must be offline.
• K2 Media Servers with role of file system/metadata server, both primary and redundant, must

These procedures allow you to keep the media database and the media files in sync. You can check
the movies (clips) in the media database for the references to media files that should be currently
stored on the media disks. Likewise, you can check for media files that are not referenced by a movie
in the media database. If you find any unreferenced files or movies, you can delete them.
Cleaning unreferenced files
