Any ideas? How can I tell fedora to use 700GB, and do I have reformat to do this?

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_computer-lv_root
                      124G  3.9G  114G   4% /
/dev/sda1             194M   23M  162M  12% /boot
tmpfs                 995M  320K  994M   1% /dev/shm

The Linux install is using LVM, so it may be that the space is there but for some reason not allocated to any volume. I suggest that you add the output of the following to your question as it may offer clues: "pvdisplay -C", "vgdisplay -C" and "lvdisplay -C" – David Spillett Aug 29 '09 at 22:24
Ran the commands and pasted the output into the question. Any ideas? – barfoon Sep 2 '09 at 17:22

Your disk is a Dynamically expanding disk right?

There is a limit of 127G for this type of disk. More details here

Hyper V 2008 R2 addresses this issue to use 48-bit LBA making max size of hard drive 2 TB. Unfortunately some Linux distro's are not seeing it. The Linux Integrated Components may help but I am not sure. I am interested in proceeding in the direction you have by using LVM with a bunch of drives (maybe even using the SCSI controller, which does see the entire 2 TB). How is LVM working for you?
