Thanks all for helping!
Problem:
NFS-Client Tru64 v5.1 with NFS-Server Tru64 v5.0
Accessing data larger than a few kB fails.
errors in messages on the client:
May 18 22:47:25 omega vmunix: NFS3 server delta not responding still trying
May 18 22:47:37 omega vmunix: NFS3 server delta ok
May 18 22:47:38 omega vmunix: NFS3 server delta not responding still trying
errors in messages on the server:
May 18 22:47:23 delta vmunix: svckudp_send: xdr_replymsg failed
May 18 22:47:23 delta vmunix: rfs_dispatch: sendreply failed IP address:
129.217.226.24
All other network operations work fine, even a NFS-import from Tru64 v4.0E
works without problems.
Solution:
John Lanier recommended to check if NFS is working over UDP or TCP, because
there are patches for v5.0 for NFS over TCP.
By checking out this with "mount -l -t nfs" i notices that wsize and rsize
were different. The NFS-import from v4.0E had wsize=8192 and rsize=8192,
but the NFS-import from v5.0 had wsize=32768 and rsize=32768. So I changed
this to wsize=8192 and rsize=8192 and everything works fine.
It seems that Tru64 v5.1 had used this options automatic, because I mounted
without giving wsize and rsize. But adding this for the imports from v5.0
solves the problem.
