Ext keeps some reserved space so that if the disk is full a root user can login and still do stuff in the reserved space. However this value is quite large. If you have a modern disk then it can be many GB of space. As its default is 5% then for example on a 2TB disk that is approx 100GB of space reserved. | Ext keeps some reserved space so that if the disk is full a root user can login and still do stuff in the reserved space.
