So what I only can do is like this in a terminal during the test is running: while true do ls -l /tmp usleep 500 done Please let me know if I am wrong. > > % df /tmp > Filesystem 1K-blocks Used Available Use% Mounted on > tmpfs 3216420 26008 3190412 1% /tmp > > What version of the kernel are you running? I am using 3.12-rc5 plus > the ext4 dev tree, so I'm using a pretty recent kernel. I'm using 3.12-rc5 plus the ext4 dev tree too. So I guess that the difference between us is that I do these tests on a hard disk rather than on tmpfs. - Zheng
