A.7 System Maintenance
This section contains topics related to system maintenance work. Carry
out the described tasks whenever necessary.
A.7.1 The Automatic Defragmentation Process
The DVS system provides an automatic defragmentation process for
the connected storage that defragments previously copied or recorded
data on the hard disk array so that they are more suited for real-time
operations.
Starting the Process
The automatic defragmentation process is automatically started to-
gether with the DVS software. It is then running in the background of
the system and will operate during stand-still times.
The process can also be started manually at any time when the DVS
software is not running (see section “Starting the Process Manually” on
page A-21).
Exiting the Process
Because the defragmentation process is automatically started together
with the DVS software, it will be exited with it as well. As soon as the
user interface of the DVS software is closed, the process will be halted
and shut down as well.
Operation
When running, the defragmentation process reorganizes the files
present on the storage during stand-still times of the DVS system. This
The automatic defragmentation process is supplemented by
the defragmenter included in Spycer which can be used, for ex-
ample, for a selective defragmentation of single clips. Further
information about this can be found in the “Spycer” user
guide.
The automatic starting of the defragmentation tool of the DVS
software can be enabled or disabled via the Configuration Tool
(see “CLIPSTER Configurations” user guide for more informa-
tion).
An automatic defragmentation will not be performed if real-
time tasks (play-out or record) are running on your system or
when the slave mode/VTR task mode is activated.
