That's because Fedora uses LVM2. Or try the README that comes with lvm2. There's also a Wikipedia article on LVM. --__________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
Take a good look at Figure 8.10 at http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/sysadmin-guide/s1-lvm-diskdruid-manual.html. The underlying file system is ext3. Here is another diagram so you can truly understand the structure behind LVM: http://tldp.org/HOWTO/LVM-HOWTO/anatomy.html.
