It is believed that errors related to the lack of free space on the server are the mistakes of novice sysadmins. But recently, it was precisely this error that caused all Toyota Motor plants in Japan to shut down for about a day, writes Nikkei Asia.

The problem arose after routine server maintenance, during an update to the spare parts ordering system. Toyota resumed operations at the facilities a day after the malfunction occurred and said it would review its maintenance procedures.

“The system was restored after the data was transferred to a server with a larger capacity,” Toyota said.

Interestingly, it was initially believed that this failure was due to a hacker attack. Most likely, the day of downtime cost Toyota several million dollars. So don’t forget to connect additional disks and make backups in time.
