Try changing the run 10 to sleep 10...

Gang,
I'm having trouble getting the 'foreach' syntax to loop through different I/O
sizes. Here is a sample of code I'm trying to get working:
#!/opt/filebench/bin/go_filebench -f
#
define file name=data, path=/filebench/local, size=128m, prealloc, reuse
define process name=randWriteProcess,instances=1
{
thread name=randWriteThread1, memsize=8m, instances=1
{
flowop write name=randWriter1, filename=data, iosize=$iosize, random
}
}
foreach $iosize in 8k, 16k, 64k
{
run 10
}
But it hangs on the second iteration:
$ ./foreach.f

[hangs forever, calling nanosleep once a second]
There are no foreach examples in filebench/workloads, so I'm wondering if other
people are having success with this.
