I tried to reproduce this as simply as possible: Server: Lucid (2.6.32-26) , nfs-kernel-server (1.2.0-4ubuntu4), nfs-common (1.2.0-4ubuntu4) - AMD based - exported fs ext4, exported like in comment #10 (rw,sync) Client: Maverick (2.6.35-23), nfs-common (1.2.2-1ubuntu1) - Intel based - target fs ext4
Connection is 1000Mbit/full duplex according to ethtool. I did the mount without any special options, just a plain "mount <ip>:/...". One thing I noticed is that 192.168.2.5:/srv/share/nfs /mnt nfs rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.2.5,mountvers=3,mountport=37472,mountproto=udp,addr=192.168.2.5 0 0 my wsize and rsize values are smaller. And I use ext4 instead of ext3. But that should hopefully be not the issue. Anyway, something seems different because I successfully copy a 4GB file without issues. So we likely need to find out exactly what the failing setup is. Has anybody running into this tried to run the actual copy from vt1 (that usually gets the console errors and may show something that does not make it into the logs)? -- System lock-up when receiving large files (big data amount) from NFS server https://bugs.launchpad.net/bugs/661294 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
