Starting the Process Manually
The defragmentation process can also be started manually, for exam-
ple, if its automatic starting during the starting of the DVS software is
disabled.
To run the defragmentation process manually perform the following:
y Open a command line (for example, via All Programs » DVS »
Maintenance » cmd).
y Type in the command avusdefrag <drive>.
y After this press [Enter].
This will start the defragmentation of the storage.
During the defragmentation process the command line window will
display the various checkings and phases of the defragmentation. Once
finished with all phases, it will start again after a certain interval.
Whether a defragmentation has to be performed is indicated by a spe-
cial assessment that evaluates the fragmentation degree of the clips on
the storage. Once a defragmentation is indicated, it will start by defrag-
menting the worst fragmented files first and align them on the storage
so that they are optimized for real-time tasks such as a play-out or a
record. In its next cycle it will take other, not so worse fragmented files
and so on, until all data is defragmented sufficiently. Afterwards in each
cycle only the checking is performed until a fragmentation is detected
once more.
A.7.2 Cleaning Temporary Data Manually
When working with the Edit Tool, temporary data may be created to
ensure a real-time capable environment. Temporary data can be proxies
and/or prerendered files, both usually written to a location on your
main storage especially reserved for this kind of data. In case you are
not sure whether the temporary data in this directory is necessary, you
can delete its whole contents manually. Afterwards you may load your
Before starting the defragmentation process manually make
sure that the DVS software is no longer running on your sys-
tem. A manually started process forces a defragmentation at
all times, meaning regardless of the state of the DVS system
(e.g. real-time operation) a defragmentation will be per-
formed. This may result in a limited real-time performance.
The default value for <drive> is V:.
To terminate the manually started defragmentation process ei-
ther close the command line window or press the key combi-
nation [Ctrl + C].
