XFileSharing Pro - Problem with HDD full

[decalnema]

Hello
I am new member and noob about sysadmin
I have one file server have HDD 2TB and install Directadmin
When I try command "df -h"
[root@server ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sdb2 9.5G 9.0G 0 100% /
/dev/sdb5 1.8T 196M 1.7T 1% /sdb4
/dev/sda1 452G 199M 428G 1% /sda1
/dev/sdb1 487M 17M 445M 4% /boot
tmpfs 3.9G 0 3.9G 0% /dev/shm

I see /dev/sdb2 full because I uploaded some file, but when that partion full, data don't write to dev/sdb5 (free 1.7Tb)

I want to ask people, What do i need config, data can write to dev/sdb5 ?

Thanks

move the website to /sdb4
or
mount sdb4 to where your website uploads folder is.
