Working on the media file system and database
Use the procedures in this section when doing configuration or service work on the
media file system or the media database of an existing K2 Storage System. Procedures
are as follows:
• “Checking the media file system” on page 516
• “Cleaning unreferenced files and movies” on page 517
• “Making a new media file system” on page 517
• “Expanding the media file system by capacity” on page 519
• “Expanding the media file system by bandwidth” on page 521
• “Backing up the media database” on page 526
Checking the media file system
This procedure checks the media file system but retains current media files. The
requirements for this procedure are as follows:
• You must access Storage Utility (via the K2 System Configuration application
login) with permissions equivalent to K2 administrator or higher.
• When you access Storage Utility, the K2 Storage System must be offline.
• All iSCSI clients and K2 Media Clients in the K2 Storage System must be offline.
• K2 Media Servers with role of file system/database server, both primary and
redundant, must be powered up but offline.
NOTE: This procedure can take 20 hours or more on a large storage system. Do not
start this process unless you have adequate time set aside.
