Franco, NFS version 2 can''t deal with files bigger than 2Gig. Perhaps you have mounted your server version 2? Try using the -o vers=3 mount option and make sure that the server''s kernel has the version 3 nfs server code compiled in.

Thanks for the advice Daire but I can assure you we never have any problems with our non Lustre patched kernels.

Anybody else seen this?You''re sure that you could before? That is indeed strange. Is this node acting as an NFS server or NFS client? -Phil

I suspect the issue could be that Franco''s system may be using NFSv2 which has=20 this as an inherent limit rather than NFSv3 which doesn''t. To explicitly mount with V3 you need to specify nfsvers=3D3 as an option. good luck!

We''re not actually running Lustre at the moment but we still have a few machines running a Lustre 1.0.2 patched 2.4.22 kernel. We noticed today that the machines running the Lustre patched kernels can''t write files larger than 2GB to NFS mounted disks. Isn''t this strange? Anybody else seen this?
