Achei essas "Release Notes" que avisam sobre problemas no dCache v1.2.2-7-1:

Release notes for Version dcache-v1.2.2-7-2
===========================================
This is another maintenance release that fixes a number of bugs meanwhile
discovered in v1.2.2-7-1, in particular
...
- confusing messages in the syslog about inode mismatch
(nfs_refresh_inode: inode number mismatch)
  solved in pnfs (RPM version: pnfs-3.1.10-15.i386.rpm)

(http://www.dcache.org/downloads/Release.notes1.6.5-2)

A versao do dCache instalado na spdc00 parece ser 1.6.6 (cf. http://spdc00.if.usp.br:2288/), bem superior a 1.2.X-X. De qquer forma, parece que o problema tem a ver com algum conflito entre o dCache e o nfs. Estou buscando mais informaçoes.

Mais uma informação sobre o problema reportado:

From the dCache developers:

Pnfs is doing some nasty tricks with i-nodes to get the
weird syntax to work ( like .(use)(1)(filename) ).
Those tricks are legal according to the nfs2/3 specs.
Nevertheless the linux nfs client impl. complains.
Though it's neasty to get those messages, they don't
do any harm (except polluting /var/log/messages).
We are not putting much effort into fixing this because
we are expecting a new pnfs implementation (chimera) in about 7 month from now.

I will close this bug now.
