The smallest one for which I observed the problem was about 600MB. For the one of 6GB is always repeatable: cp folowed by cmp reports always differences in the files. >>It may be a hardware problem but I somehow doubt it. > > > /var/log/messages? nothing relevant, the hard-disk does not seem to have bad sectors or something like that. > > >>reiserfsck says No corruptions found. >>The system is SuSE 9.0, kernel 2.4.21-273-smp4G (it is a dell poweredge > > > so, this is reiserfs3, right? did you use the current reiserfsprogs? yes, reiserfs3. I use reiserfs 3.6.9 delivered with SuSE 9.0. Do you think a newer version would help? To me the problem seems to be in the kernel not in the utility programs. Anyway is anybody interested in investigating this problem further? I can make a complete dump of the partition (it's about 80GB), such that it can be used in loop mode for test. I will also make some tests with the parition in the loop mode on another computer. Otherwise I inted to reformat completely that partition (should I still use reiserfs3? somehow I don't trust it anymore). mache
