Clients 64 bit. Server 32 bit. When I try to copy or stream a large file greater than 35 MB, from an nfs-mount to my local harddisk, the transfer stops after 35 MB and on the server machine I can see 3 or 4 nfsd processes whith 99% cpu-usage all together. I've stopped that after 4 Minutes with ^C on client and "rcnfsserver restart" on server. I've tested with NFSv4 and v3, sync and async option in /etc/exports and fstab. Please let me know, which informations I should provide, to solve this problem. Reproducible: Always Steps to Reproduce: 1.on server: nfs-export a directory with one or more large files in it. Can be any structure 2. on client mount the nfs-directory anywhere. Have enough local diskspace, to store the large file. 3. on client: copy a large file from nfs-mount to localdisk. Actual Results: it transfers and stores max. ~ 35 Megabyte on localdisk. Client waits for more Data and freeze (on KDE only the terminal or the filemanager). Server uses his complete CPU with 3 -4 nfsd processes Expected Results: should copy the data with full network speed in 1 minute. I've found no relevant entries in /var/log/messages, targeting nfs errors. A test, doing the same copy with "scp user@server:/dir/file ." on the commandline was successfully done - 1.5 GB on full speed - so the network is ok. There must have something changed in the NFS-Server since OS 11.3, where it works with the 12.1 clients accessing the 11.3-server. Curious: the server has 2 NICs, eth0 and eth2. It is connected via eth0. But when I run nfswatch without parameters, it displays the stats of eth2. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
