The developer reported that they were unable to access the database, and all their attempts to log in had failed. John quickly checked the system logs and found the following error message:

Fatal: Role root does not exist

John knew this was not good news. The root user is the superuser in a Linux system, and without it, nothing can be done. John realized that somehow, the root user's account had been deleted or disabled.

John checked the system backups, but unfortunately, the last backup was from Friday, and it was already Monday. John knew he had to find a solution fast, or the company would suffer significant losses.

John started to investigate the cause of the problem. He discovered that one of the junior system administrators had mistakenly run a script that had deleted the root user's account. The script was supposed to clean up old user accounts, but it had gone wrong, and the root user's account was deleted instead.

John knew he had to act fast; he re-created the root user's account and gave it the necessary permissions. He then started to restore the data from the last backup.

It took John several hours to restore the data, but finally, everything was back to normal. The developers could access the database, and the company's business operations resumed.

Point of View: Empathic Voice and Tone

The error message Fatal: Role 'root' does not exist can be extremely stressful for a system administrator. It implies that the superuser account has been deleted or disabled, and without it, the system cannot function correctly.
