This command starts a diagnosis and correction of the file system. It is very useful in cases of disk corruption. To perform this operation, begin by connecting to your server via SSH or console (not applicable for Gandi AI). You may then type the following command:

fsck

Once launched, the application will ask you several questions that you will need to answer. For the most part, it is simply a confirmation asking you for permission to delete a corrupted file. It is therefore possible that this will result in the loss of some data.
