We in fact on many occasions ran into such problems. To the OP, if you're 64-bit everywhere there's no problems so enjoy the benefits of XFS ;) -- James A.

We in fact on many occasions ran into such problems. To the OP, if you're 64-bit everywhere there's no problems so enjoy the benefits of XFS ;)I too have seen this issue, in both NFS configurations (exporting the root or exporting subdirectories using fsid). We only have one 32bit NFS client left, so I simply tell people not to use it (the work it does is mostly on local filesystems). --keith -- kkeller at wombat.san-francisco.ca.us
