http://bugzilla.kernel.org/show_bug.cgi?id=13201 --- Comment #9 from Theodore Tso <tytso@xxxxxxx> 2009-06-08 16:49:28 --- If this is the same problem as the one which we fixed with identical symptoms, what matters is multiple processes/threads writing to the same file at the same time. People using NFS or SAMBA on a backup server seemed to be a most common scenarios for triggering this (admittedly very hard to reproduce) bug. We finally got lucky in that someone had a setup which allows for reliable reproduction of the bug, so we could finally sink our teeth into it. So if what you saw was the same as the bug we fixed in 2.6.30-rc6, no it shouldn't make a difference. If it is a completely different bug, then of course all bets are off. In general though whether you are writing to one filesystem or 4 filesystems shouldn't make a difference, except in that it might change the timing necessary to hit a race condition (and in the case of the bug that we found and fixed, it was highly timing dependent; in fact, even after we found the problem, we weren't able to come up with a reliable reproduction case, even though the problem was obvious on paper and the one user who could reliably reproduce reported it went away once the patch was applied; IIRC, Eric finally put in a delay into the code to widen the race window to the point where he could replicate it.) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
