IOError: No space left on device - which device?

Question

I\'m uploading a small file (8.5 Mb) to a flask test server.

When the file finishes uploading, the server reports:

    File \"/home/ubuntu/.virtualenvs/e         


        

Answer 1

Try df -i , maybe there are no free inodes.

EDIT:

another option, find werkzeug pid, let it be 777,

• run strace -p 777 &> /tmp/strace_log
• try to upload a file
• stop strace
• find that No space left on device message, it will be like write(1, "blah blah ..."..., 57) = -1 ENOSPC (No space left on device) first argument to write is a file descriptor
• go up and try to locate specific open(... = X syscall , that X is a file descriptor that will fail in "write" syscall step

Pretty cumbersome, I know, but that's debugging.
