Experience saves data for Tatort, Traumschiff & Co
A continuation of our original success story, however, in support
RAIDdeluxe with SUPPORTdeluxe
Studio Hamburg Postproduction GmbH works on many TV formats such as "Tatort", "Notruf Hafenkante" and "Großstadtrevier". A large amount of data storage is always required for the filming material or raw material.
Starline had already supplied a RAIDdeluxe storage system including two JBODs for this purpose years ago. The total of 1.25 petabytes worked perfectly for years until two hard drives in a raid set failed in April of this year, which statistically does not happen that often.
The raid sets have a RAID6 level, which means that a maximum of two HDDs can fail at the same time. One HDD was then replaced with a new one and the rebuild process started.
This is done so as not to overload the RAID with a double rebuild. Unfortunately, two more hard disks failed in the process. This meant that all data on the RAID was completely lost at that moment.
E-shots on the edge
Support for the RAID had expired in the meantime. However, all the data on it, approx. 800 TB, was backed up twice on LTO7, so the loss of the RAID would have been annoying but bearable.
The establishers (e-shots) were also affected by the RAID failure. These film snippets are required for series that take place at recurring locations - such as "Tatort" or "Großstadtrevier". Here, houses or streets are filmed once so that they can be economically incorporated into further episodes at a later date.
Once these establishing shots are shown, the viewer knows immediately where the storyline will continue. This treasure trove of film sequences was therefore under threat, or at least could only be reconstructed with a great deal of manual labour.
Our solution
Joachim Sommerstedt therefore contacted our RAIDdeluxe expert Konrad Beyer directly. He had some suggestions for solutions, but these did not initially produce the desired results. As a result, the system was in danger of being cancelled forever.
Finally, the technology veteran had a riskier but promising option: he had the support engineer switch off the device and reinstall the old, previously failed drives in their original positions. After the restart, there was understandably no intact RAID set. He then deleted the affected RAID set and recreated it without initialising the RAID set.
