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.

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.
