A server, to which I only have remote access has a raid with lvm and reiserfs partitions on it. I will limit the information to the /home partition in the following, other partitions have the same problem. All information is taken from a rescue system (PXE boot), which is offered by the provider. Booting into the rescue system, I can get the following information:
root@rescue ~ # vgdisplay

If I now boot into the actual system, not the rescue system, I get:
kermit:~# vgdisplay

Now for the not-so-funny part:
kermit:~# df -Th /home/
Dateisystem Typ Größe Benut Verf Ben% Eingehängt auf
/dev/mapper/systemlvm-home
reiserfs 14G 649M 14G 5% /home
kermit:~# lvm version
LVM version: 2.02.39 (2008-06-27)
Library version: 1.02.27 (2008-06-25)
Driver version: 4.13.0
What is wrong here? I am not sure if the problem really lies within LVM, but it is my best guess so far ...
The same problem appears on the other lvm volumes as well.
Thanks for ANY hint!
