I installed the patched kernel and xen RPMS this morning and can confirm that this fixed my problem. I can now see my 2.7TB partition correctly in the DomU guest. Thanks to all for the quick fix, and to Dan for help with building the modified kernel RPM. R. -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
