Date: Tue, 3 Mar 2009 21:05:31 +0100 From: "Andries E. Brouwer" <Andries.Brouwer@....nl> To: linux-kernel@...r.kernel.org Subject: ext3 duplicate entries with readdir In a largish directory (21292 files) a scan using ext3 readdir found 21293 files, returning one entry twice. Google "ext3 readdir twice" gives me a handful of identical complaints. I see reports from 2002-2008. So, this is an old and well-known symptom but seemingly still not fixed, at least not in the kernel on this machine here. This report is for Fedora release 8 (Werewolf) with kernel 2.6.24.5. A 2002 post says "This is unfortunate, but the chances of our hitting this failure are relatively small". In http://www.redhat.com/archives/ext3-users/2008-August/msg00009.html tytso seems to understand what happens: a hash collision. But has this been fixed in the current tree? Andries Thomas Trauner gave a test program. It prints expected 25989 files, but readdir reports 25990 So, yes, this is reproducible. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
