linux df and OSError: [Errno 28] No space left on device

Question

I've got a weird inconsistency (although I'm probably just missing something quite basic). While running some script that generates small files on my I disk, I constantly get this error:

OSError: [Errno 28] No space left on device

But when I run df -h, I get:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              15G   12G  2.2G  85% /
udev                  502M  144K  502M   1% /dev
none                  502M     0  502M   0% /dev/shm
none                  502M   72K  502M   1% /var/run
none                  502M     0  502M   0% /var/lock
none                  502M     0  502M   0% /lib/init/rw

So am I low on disk-space or not?

Thanks for any input!

You're probably out of inodes. Try df -i.
