Transferir grande quantidade de dados/Transfer large amount of data

Instalei o Nextcloud no Raspberry PI e coloquei o /data no HD externo, tenho cerca de 1.5TB de dados. Como faço para os dados aparecerem na nextcloud? Sendo que eu passando eles para a minha pasta dentro do /dados, ele não aparece lá.

I installed Nextcloud on Raspberry PI and put / data on the external hard drive, I have about 1.5TB of data. How do I get the data to appear in nextcloud? Since I pass them to my folder inside / data, it does not appear there.

Did you run php occ files:scan --all

Gave a error
PHP Fatal error: Allowed memory size of 2097152 bytes exhausted (tried to allocate 32768 bytes) in /var/www/html/nextcloud/3rdparty/composer/autoload_static.php on line 411

I found out what’s going on, it’s because I’m using raspberry pi 3, it only has 1GB of RAM, I tested desktop raspbian with 2GB of RAM and it worked sudo -u www-data php occ files: scan --all
