LVM ver 2.01.08 (2005-03-22)
Library ver 1.01.02 (2005-05-17)
Driver ver 4.4.0
Fedora Core 4 with 2.6.13-1.1526 kernel
hda are the system essentials; /boot, /, and swap
hdb, hdc, hdd are the LVM disks. Each disk contains 1 primary type 8e partition from beginning to end of disk.
Also, recently while I was tinkering with it I attempted a 'vgcfgrestore bloaty' and received:
Couldn't find device with uuid 'tfkC8Z-sWLe-09A5-1Yow-qKw1-0DZz-x73mWt'.
Couldn't find all physical volumes for volume group videovg.
Restore failed.
I surmise that that uuid belongs to hdb1. Would this be the appropriate point to restore pv metadata?

If I've omitted anything please let me know.
Thanks again,

Hi all,
I'm in a pinch. I've got about 500Gb of data trapped in a non-functioning VG... Here's the deal:
I upgraded from FC3 to FC4, or tried to. The whole update bombed out but during this time the LVM disks were unplugged from the system. When I got the new system up on the old FS my LVM conf still appears to be in place. I powered up the 3 drives and reset the system and I found the VG won't activate.
I did not export the volume first. I realize now that this was a mistake.
I have 3 whole disks for this VG, each with 1 partition, type 8e, occupying the entire disk. These are hdb1, hdc1, hdd1.
I'm noticing that an "fdisk -l" lists hdb, hdc, and hdd as all having partitions of type 8e from beginning to end of disk. However, when I go into LVM and run "pvscan" I only see two PVs belonging to my VG "bloaty" and it shows:
PV /dev/hdc1 VG bloaty lvm2 [111.78 GB / 0 free]
PV /dev/hdd1 VG bloaty lvm2 [115.03 GB / 64.00 MB free]
Total: 2 [266.81 GB] / in use: 2 [226.81 GB] / in no VG: 0 [0 ]
LVM doesn't seem to notice /dev/hdb1? It's a 232.88 Gb PV, how can this be? And why isn't PVSCAN complaining about a missing PV? It should be, shouldn't it?
When I perform a "lvmdiskscan" I get (the parenthesis outline my input):
/dev/hda1 [ 101.94 MB]
(^^this is the /boot partition)
/dev/hdc1 [ 111.79 GB] LVM physical volume
/dev/hda2 [ 17.54 GB]
(^^this is the / partition)
/dev/hda3 [ 1.00 GB]
(^^this is the swap partition)
/dev/hdb1 [ 232.88 GB]
(^^THIS SHOULD BE A PV)
/dev/hdd1 [ 115.04 GB] LVM physical volume
Is there some trick here I don't know about? Do I have to restore the LVM conf?
I am stumped. I'm pretty sure I'm not a newb, but I am definately not a wizard. I've got my LPIC Level 1 cert if that means anything.
Heh, thanks for any help,
Cory
