This may not be a CentOS problem, because I'm in a mixed environment.
But I put it out in case anybody has any thoughts.
I recently replaced a file server, which was on a Pentium III based
system running 32-bit CentOS 4.3, with an Opteron based system
running Fedora 4. The NFS clients are all CentOS 4.3, some are 32 bit
and some are 64 bit.
Since the replacement, when I try to write a big file from the 32bit
CentOS boxes over NFS to the server, I get "filesize exceed
messages" at 2GB. However this used to work with the old server. And
I can write big files if I'm logged on to the server.
One more oddity, the shared file system on the server is xfs
formatted; if I instead mount a reiserfs file system I can
successfully write. This part does not make sense to me.
And one more, I can write large files from a 32-bit Fedora 4 system
to the server over NFS, just not from 32-bit CentOS.
I'm exporting with (rw,async) and mounting with
(bg,rsize=8192,wsize=8192)
Is there some interaction between nfs and xfs that I need to know about?
Thanks,
