No space left on device solution

When I uploaded a file today, NGINX reported an exception. By checking the NGINX log, I found the error No space left on device was reported. Because the pressure test of the uploaded file has been done in the past two days, many temporary files have been generated.

solution:

df -h  ##查看磁盘空间情况

   

Found that the disk is full, delete the temporary files to solve it.
