What's the status of this page: http://www.freebsd.org/projects/bigdisk/ Is it still updated? Is the information on this page still correct? It's not linked from the main projects-page, AFAICS. From this thread, I assume it's now possible to have >1 (or 2 or 4) GB partitions, just that sysinstall would have to be taught about gpt. If I have a 4TB array (e.g. on a NetApp) - can I mount that via NFS, or is there a problem? Or what about exporting an array of that size via NFS from a FreeBSD-host - does that work? cheers, Rainer
