disk stats are not printed

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I have tried various options for running the Disk tests like below but the 
stats is not printing the disk and data check performance numbers after the 
test runs.

./stressapptest -d /dev/sdb -s 10 -v 20 --destructive

./stressapptest -d /dev/sdb -s 10 -v 20 --destructive --findfiles
./stressapptest -d /dev/sda1 --write-block-size 4096 -v 20 -s 10 --destructive

./stressapptest -d /dev/sda1 --write-block-size 4096 -s 10 --destructive

What is the expected output? What do you see instead?
The disk stats & data check should print some number 

Stats: Found 0 hardware incidents
Stats: Completed: 72356.00M in 10.00s 7235.11MB/s, with 0 hardware incidents, 0 
errors
Stats: Memory Copy: 72356.00M at 7235.34MB/s

Stats: Net Copy: 0.00M at 0.00MB/s
Stats: Data Check: 0.00M at 0.00MB/s
Stats: Invert Data: 0.00M at 0.00MB/s
Stats: Disk: 0.00M at 0.00MB/s


What version of the product are you using? On what operating system?
stressapptest-1.0.6_autoconf on ubuntu 
Linux host2 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 05:14:15 UTC 2010 
x86_64 GNU/Linux
Ubuntu 10.04.1 LTS

Please provide any additional information below.

Please let me know how can we get the disk and data check numbers. I have tried 
a lot of options in the 1.0.6 build.

There's a few issues here: 

"Data check" refers to read-only check threads, from the "-c" argument. 
stressapptest checks all data so it's not necessary to use this argument.

You must not use "-d /dev/sda1" and "-f /mnt/sda1/file" at the same time as 
they each require exclusive access to the referenced disk region. "-d" will 
overwrite the filesystem on sda1 and conflict with the file used by "-f".

However, "-f" should cause a nonzero number in "File copy" and "-d" should 
cause a nonzero number in "Disk". I'll run some of your command lines and see 
if I can reproduce.

Hi Nick,
Thanks for the quick replies :).

In this example below I am using the -d option with -c below. No Data check or 
disk numbers are printed.

"-c" requires an integer number of threads to run, such as "-c 4"

Thanks Nick, The data check numbers are getting populated now. Only the Disk 
ones are remaining.

Hello~
I have one question, I have try to run my command:
#stressapptest -s 172800 -M 1024 -m 8 -i 8 -C 8 -W -n 127.0.0.1 --listen  -f 
/tmp/file1 -f /tmp/file2 -d /dev/sdb -c 4 -l  /var/log/stressapptest.log

But I still cannot get Stats:Disk result.
How can I get the Disk result?
