Seafile User storage not match with system storage

Today, I am encountering a peculiar issue. One of the users in Seafile is exhibiting a usage of 456.0 GB, whereas the total disk usage of the operating system is only 259 GB. I have thoroughly investigated the matter using various methods, but I have been unable to identify the root cause.

I kindly request anyone who can assist me in resolving this problem to come forward and provide their support.
