Toyota has blamed a recent shutdown of all of its factories in Japan on a system malfunction caused by “insufficient disk space”.

The Japanese carmaker said the stoppage on 29 August at all 14 of its domestic plants occurred after servers that process orders for vehicle parts broke down following a maintenance procedure carried out the previous day.

During this operation, “data that had accumulated in the database was deleted and organised, and an error occurred due to insufficient disk space, causing the system to stop”, Toyota said on Wednesday.

Seen a similar thing on site historians which collect large amounts of data, typically the client wants all possible data available, but then never goes through the historical data to delete what is not required, or they set silly retention policies (two years for example) and then suddenly disks are 100% full and everything grinds to a halt. It's not a massive pain if you run a redundant set up and the historian runs on it's own dedicated server, but I've seen instances where historian runs together with SCADA on the same server and then everything just stops (likely what happened in this particular case).
