The bug : https://bugzilla.redhat.com/show_bug.cgi?id=469848 The link itself explains quite well my issue, I'm just truing to copy a big file (36Gb) to my nfs server and when I try to get an ls -l command to the same folder where I'm copying data, the command gets stuck for some time. This amount of time changes from a few secs to SOME minutes (9' is the current record). I can live with some seconds of delay, but minutes is something quite unacceptable. As this is an nfs server running on a red hat system (an HP ibrix x9300 with Red Hat 5.3 x86_64, kernel 2.6.18-128) I was told to apply the patch suggested from the bug on my clients. Unfortunately my clients are running fedora core 14 (x86_64, kernel 2.6.35.6-45) and I can't find the file that they are referring to, the file fs/nfs/inode.c is not there and I can't find the rpm that contains it. As the bug is a very very old one, I took it for granted that is already applied to fedora, but I wanted to make sure that it is looking at the file. Can you help me on this? I'm I wrong in my supposition (is the patch really applied)? is it possible that my problem is somewhere else? Thanks a lot in advance for your help, please let me know if I can provide any more information. j
