Terribly sorry for the double post to the mailing list, accidentally hit the
google shortcut.

I have been using LVM for several months to record video files for my PVR
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,

Argus

I've been digging around a bit and I found that /etc/lvm/archive has some
information that might be useful for restoring my LVM data.

I've attached the latest VGforMythTV_00008.vg data (before the versions for
the new ones that I created).

I read on this blog:
http://codeworks.gnomedia.com/archives/2005/general/lvm_recovery/

that this information could be used to recreate my physical volumes using a
command like this:
[mythtv@localhost archive]# /usr/sbin/pvcreate -u
J3hQY6-8yfK-pMPS-dGhN-WFig-ENnC-LSR2nn /dev/hdb1
  Can't initialize physical volume "/dev/hdb1" of volume group "VGforMythTV"
without -ff

I am hesitant to use the "-ff" (force) command without knowing what the
impact will be.  Any advice?

Thanks,

-Argus
