I really don't remember what the problem was. It was about 2003 or 2004 I think that I came across the issue. I don't recall if it was XFS or ext2/3 or what.
I just know I came to the conclusion that dd if=/dev/sda of=/dev/null was not always safe if the drive had a mounted filesystem. Hopefully its been fixed by now.
2.4.x? If yes, I am not so surprised since buffer cache and page cache aren't unified yet, unlike in 2.6.x. I highly guess that was indeed synchronization issue.... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
