Package: iozone3
Version: 397-2
Severity: normal
Hi,
The command:
iozone -a -B -+d
always fails within seconds and reports "Error in file". I tried this
on four different amd64 machines, on ext3 on rotational media, on ext4
on SSD, and on tmpfs, and it always fails at the exact same address,
so it is not a hardware problem.
Full log:
$ cd /tmp
$ iozone -a -B -+d
