I doubt that you have actually deleted any data. If the partitions are still there, it will just be a matter of fixing the LVM. I am not sure, but FC3 may have been LVM v.1 and FC5 is v.2
Do a google search for lvm 1 to 2 upgrade. Also, it is possible to re-form your LVM through manual commands. No guarantee on getting the data back, but it should be do-able.

Subject: [mythtv-users] LVM problem upgrading to FC5
I realize this is only tangentially related to mythtv, but I haven't gotten any help from the linux-lvm list which seems pretty quiet.
I have been using LVM for several months to record mythtv files across a 200GB and 160GB disk (hdb and hdc).
Recently I decided to upgrade my FC3 install to FC5. After the install, my LVM mount does not come up. It appeared that all of the LVM information in /dev/ was gone; however, only the non-LVM drive (/dev/hda) should have been touched by the FC5 upgrade.
This is my fstab entry:
/dev/VGforMythTV/video /var/media xfs defaults 1 1
This is what fdisk shows:
/dev/hdb1 1 24792 199141708+ 8e Linux LVM
/dev/hdc1 1 19929 160079661 8e Linux LVM
In my attempt to fix this, I think I may have totally fouled things up; I tried to create a new volume group with the same name and more PVs for the new drives, then combine them together into an PV with the old LV name. However, this still does not allow it to mount.
Any ideas? Have I deleted all my data?
Thanks for any help,
I've pasted my history commands below.
552 /usr/sbin/pvcreate /dev/hdb1
553 /usr/sbin/pvcreate /dev/hdc1
554 /usr/sbin/vgcreate VGforMythTV /dev/hdb1 /dev/hdc1
555 mount /dev/VGforMythTV /var/media
556 mount /dev/VGforMythTV/video /var/media
558 lvcreate --name video VGforMythTV
559 /usr/sbin/lvcreate --name video VGforMythTV
560 /usr/sbin/lvcreate --name video -l VGforMythTV
561 /usr/sbin/lvcreate --name video -l ` VGforMythTV
562 /usr/sbin/lvcreate --name video -l 1 VGforMythTV
563 mount /dev/VGforMythTV/media /var/media
564 mount /dev/VGforMythTV/video /var/media
565 mount -t xfs /dev/VGforMythTV/video /var/media
566 mount /dev/VGforMythTV/video /var/media
567 /usr/sbin/lvcreate --name video -l 2 VGforMythTV
571 mount /dev/VGforMythTV /var/media/
572 mount /dev/VGforMythTV/video /var/media/
573 mount /dev/VGforMythTV/media /var/media/
574 mount /dev/VGforMythTV/video /var/media/
(none of these last commands worked -- there is no sign of the original data, but I have now created the VGforMythTV volume group but it only shows my two new logical volumes, but not the original one with all my data).
