Docker keeps saying "No space left on device" when there's space in device

i have two volumes attached to my ec2 instance, one is /dev/sda1 which is root volume and it is 8 Gb while there's another volume /dev/sdb which is 500GB. I can see both volumes when i run sudo fdisk -l. I have a django server running in docker instance running on this ec2 instance and when i upload some data to server docker "I/O error, no space left on device". How can i fix this problem?

EDIT

Following is my docker-compose.yml
