This is due to an issue with checking permissions on a ftruncate, it's a bug that I'll hopefully get time to poke at myself if someone doesn't beat me to it. In the meantime, run iozone as root. (However that doesn't help Lassi, just FYI for others.) -Josh On May 3, 2010, at 5:22 PM, Lassi Tuura wrote: > I can use the basic system fine.
