[linux-lvm] Minor LVM bollixment - /dev/dm-xx doesn't contain a valid partition table



Last week, my wife rebooted our web server with the reset button
(don't ask).  It booted ok and appears to be running fine, but now I
get this result from "fdisk -l"

Disk /dev/hda: 80.0 GB, 80060424192 bytes
255 heads, 63 sectors/track, 9733 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

The /dev/dm-nn correspond to the 12 logical volumes in that VG.

I checked dmesg and found this:

EXT3-fs: dm-0: orphan cleanup on readonly fs
ext3_orphan_cleanup: deleting unreferenced inode 1094899
ext3_orphan_cleanup: deleting unreferenced inode 227777
ext3_orphan_cleanup: deleting unreferenced inode 1078122
ext3_orphan_cleanup: deleting unreferenced inode 1466022
ext3_orphan_cleanup: deleting unreferenced inode 617737
ext3_orphan_cleanup: deleting unreferenced inode 617736
ext3_orphan_cleanup: deleting unreferenced inode 617735
ext3_orphan_cleanup: deleting unreferenced inode 617733
ext3_orphan_cleanup: deleting unreferenced inode 1239631
EXT3-fs: dm-0: 9 orphan inodes deleted
EXT3-fs: recovery complete.
EXT3-fs: mounted filesystem with ordered data mode.

There's nothing in /lost+found.  Several LVM tools I tried, including
vgck report nothing amiss.  vgscan, lvscan, vgdisplay all provide
normal output.

The system is FC4, updated nightly with yum.  lvm RPM is
lvm2-2.02.06-1.0.fc4.  A Google search didn't turn up anything useful.

As I noted, it's running fine, apparently, though, fdisk seems to
expect partition tables in /dev/dm-nn.  How do I fix this short of
setting up a new drive and copying everything over?

Cheers,
