I know that message from my tests with graid5...
It was clearly caused by a bug in graid5, but I cannot remember when or why it
happened...
I would guess, it happened because of some cache or request-sorting
mismanagement (the write didnt take place but the read was executed; or the
second write took place before the first write)... Is that possible in
gvirstor? Does newfs create such a request-pattern (overlapping write requests
<-- would be a little bit astonishing)?
But I can definitely say, that it was a bug in graid5...
Just my 2 pennies...
Bye
Arne
