Istvan, thanks for the response. All other disk-intensive processes cause the xfs partition no problems, other than NFS. I can scp, rcp, rsh, and rsync to and from the XFS partition perfectly. I can also copy large files to and from it locally with no problems. The server seems to hang only when I transfer large files via NFS to or from the xfs partition. I can, for example, cp -R a directory that is 1G to the xfs partition as long as each file within the directory is less than about 200M. However, a cp of a single file that is 260M freezes the server every time.
Thanks for any insight you can give me.

Hello all, I'm having a problem with nfsd (from Mandrake 9.0 install 2.4.19 kernel) on xfs partitions. I am running an IDE RAID5 with 3Ware's Escalade 7500 controller. The xfs partition as 1.1T. I can transfer large ammounts of small files on to the xfs partition without any problems, but as soon as I try to transfer a large file to the partition, the entire server freezes when about 200 megs have been transfered. At this point, the server is completely frozen and can only be restarted manually. I can, however, transfer large files to the same server, but on to a smaller 100G ext3 partition. Ideally, I would like to find a work around the issue without having to re-format the entire RAID. Any help would be greatly appreciated.
Mark,
Try narrowing it down a bit. Are you able to reproduce the hang when you copy file without using NFS, for example using rsync? How about just using something like dd if=/dev/zero of=//file/on/xfs/partition?
If yes, you might want to ask on the XFS list or see if it's related to the hardware you use.
For what it's worth, I have 3 NFS servers using XFS, each with 340GB SCSI hardware RAID disk and they have been running for a few months now with little problems. With older kernels (around 2.2.18 or 19pre) I had crashes once every few weeks but with 2.4.20 so far no problems *knock on wood*
