Question on XFS - somewhat newbie

[bcc@xxxxxxxxxxxxxxx]

        I've installed the XFS 2.4.18 kernel and 2.0.6-0 xfs utilities on 
        a Redhat 7.2 machine (was patched all the way as per Redhat's
        errata) following the instructions on the SGI website.. The machine 
        runs the Enterprise kernel (large memory support), so I used the 
        generic one from the download page to upgrade. The machine booted 
        fine and runs well, but the only way I can get a large file on the
        new xfs partition is to use the xfs_mkfile command. I've tried
        ftp, rcp, and even local scripts on the machine to copy/create a
        file bigger than 2gb, and all options keep failing. Any advice/
        suggestions to resolve/work around this are greatly appreciated. 
        Thanx.
