Hi Jens,
The reason for saying ext3, is I run fdisk on /dev/cciss/c1d0 and created a primary partition.
 
Then I created a ext3 filesystem on this partition by running mkefs and mounted this partition on /mnt folder. Then I run fio on this partition.
 
We earlier use to run fio on raw partition. But now we tried running fio on a partition which has ext3 filesystem.
 
When I run fio on raw filesystem I dont get any errors for Sequential Writes, but when I run fio test on this ext3 filesystem then I am getting the errors for Sequential Writes what I mentioned u earlier.
 
Thanks,
 Girish

Don't apologize for that. But if there's something I write you
don't
understand, do just ask for an explanation.

So my current question is why you are mentioning ext3? The test case you
provided is reading and writing directly to the CCISS device, not a file
inside a file system hosted on that device.

Also, please try a make clean && make && make install in your
fio
directory. Sometimes things get hosed when updates are pulled, which may
explain why yours is acting up.
