The problem appears when I write big files relatively fast over nfs. My client is Dual-Athlon 1900+, and the servers are Dual P3 500MHz (with 2.4.18) and Pentium 2 200MHz (with 2.4.18 debian bf-2.4 default kernel). Both servers use kernel-nfsd. However, as things work perfectly with a 2.4.19-client and between the servers, it would hardly seem to be a server-matter. There is a gigabit-link between the Athlon and P3. Reproducing: dd if=/dev/zero of=new-file-on-nfs-file-system -> dies on I/O error. If I dd if=/dev/zero bs=1024 count=1000000 of=existing-one-GB-file, things fail similarly. (Last attempt failed at record 3073.) It might be just luck, but it would seem to me that the Dual-P3 server behind the gigabit-link fails faster than the slow P2-server (which is infact network-topographically behind the P3). Relevant lines from .config: CONFIG_NFS_FS=m CONFIG_NFS_V3=y # CONFIG_ROOT_NFS is not set CONFIG_NFSD=m CONFIG_NFSD_V3=y # CONFIG_NFSD_TCP is not set CONFIG_SUNRPC=m CONFIG_LOCKD=m CONFIG_LOCKD_V4=y I'm willing to try patches :). -- _____________________________________________________________________ / __// /__ ____ __ http://www.modeemi.fi/~flux/\ \ / /_ / // // /\ \/ / \ / /_/ /_/ \___/ /_/\_\@modeemi.fi \/
