[BBLISA] NFS lock problem between Mac OS X and netapp (amongothers)

[Joshua Putnam]

At our midsize software company, we have worked around numerous NFS
locking issues (and other NFS issues) with networking Macs into our NFS
environment.  Some of the issues seem to be related to the non-standard
NFS packet size used by OSX.  

I concur that these issues are more prevalent in 10.3 and earlier than
in 10.4 and later.  Also, we had more problems connecting OSX NFS to
Netapp storage than any other platform.

The following may be helpful:

This page has a Linux patch that is supposed to resolve Linux/OSX NFS
problems:

http://client.linux-nfs.org/Linux-2.4.x/2.4.23-rc1/

This page links to Linux patches, as well as a patch for the rpc.lockd
on the OSX host:

Hope this helps!

I few months (?) ago, I mentioned having issues with nfs between Mac OS
X <-> Linux.  This came up in the context of a discussion about iSCSI.

At that time, our biggest (NFS) pain point was FC3 being an NFS client
to MacOS X 10.3.  It wouldn't hold up under even moderate I/O -- forget,
say, doing compiles across an nfs mount.

These days, we've moved on to CentOS 4 and Mac OS 10.4.  That's has been
a much more solid combination.  But I haven't paid close enough
attention to know which OS vendor to thank.

Is that the issue you were referring to?
