Local External Storage after mount


I have added an external storage after mount hard drive with these commands :
mount /dev/sda1 /mnt/DATA/
chown -R nextcloud:nextcloud /mnt/DATA/
chmod -R 0750 /mnt/DATA/

After that, I see my hard drive on the web site, fine :slight_smile:

After that, I umount the storage, on the web site, I see “No files in here”. It 's normal.
(If I unmount, it’s because I can get my external hard drive out of nextcloud…)

But if I mount the storage, on the web site I still see “No files in here”.
However, with ls comand, I see my storage with all file.

How can I automatically refresh the directory of the mount point after mount ?
