Errors writing large files via NFS

[godhelp]

Managers,


We have a strange problem (aren't they all?), where we are unable to copy files larger than a certain size to a NFS server. This server exports a filesystem (/archive) to a number of other Tru64 boxes. The problem of being unable to write large files to this filesystem shows up on all the client systems, although the definition of "too large" varies. Some of the clients are on the same network as the server, and access it through a lag interface. The other clients are in another data centre and connect through
a WAN link via a single (non-lag) interface. Since there are quite distinct network paths involved, I'm pretty sure we're not seeing a network problem.

We are pretty sure that it is it an NFS problem, and not the filesystem nor any other network later, since there are no problems with using 'rcp' to copy files onto this server. And yet the same file, copied from the same
client over the same network connection, to the same location, will fail to copy successfully if we use 'cp' to copy it to an NFS mount.

any inputs..

What version of NFS are you using on your servers v2 only supports up to 2gb. What do your options in your export file for your filesystem look like (/etc/exports).
