В папке пусто, но из неё грузит

Centos, 480gb SSD x 2 - mirror

На сервере 2 SSD диска по 480GB, один зеркальный другого.

Зашёл в одну из папок , а там пусто. Но в ней должно было быть около 10-ти папок. Из web грузит, но через ssh или ftp папок не видно. Странное дело.

В чём может быть проблема, подскажите пожалуйста?
