Hi, Noons,

    It is the first time I know about this:
>>I've got a funny feeling you just hit the 32K default Linux I/O
limit.
>>You see, until kernel release 2.6 (or patched 2.4), Linux will
>>"secretly" transform any single I/O request for more than 32K bytes
>>into as many 32K requests as needed

   Can you provide some detail about this? For example, metalink id, or URL about linux kernel about this.

And Utkanbir, since it is for test, can you shutdown one node and perform your test again?
