Hi lists! My fileserver stored it's data on 3 physical disks,building a volumegroup with lvm2. The mashine was running ubuntu dapper drake for a long time without any problems but I decided to switch to ubuntu feisty fawn. Switching from debian to dapper drake I installed and removed quite a lot of packages, leaving a messy system, so I thought a new and clean installation with feisty fawn might be a great idea. box config with dapper drake: hda: 120GB (PATA) systemdisk hdb: unused hdc: 250GB (PATA) part of the LVM-array hdd: 250GB (PATA) part of the LVM-array sda: 400GB (SATA) part of the LVM-array sdb: DVD-RW (PATA on additional PCI-controller UDMA-100) The additional IDE-controller was installed to be able to install even more disks, but as I won't buy any new PATA stuff the controller was dispensable. new box config: hda: 120GB (PATA) systemdisk hdb: DVD-RW hdc: 250GB (PATA) part of the LVM-array hdd: 250GB (PATA) part of the LVM-array sda: 400GB (SATA) part of the LVM-array I exported the vg before shutting down dapper drake and while installing festy fawn to the box I - no idea what did me do so - installed grub to hdc. Ooops, this disk was part of the LVM array and so grub f*cked up the lvm meta-data on hdc. After installing grub to hda the box is running fine, despite the LVM which can't find one of the vgs volumes: Code: bigmac@knecht:~$ sudo pvscan Couldn't find device with uuid '9kpWwu-LdwT-YiqV-DRPg-kSAN-plYN-v1Eq81'.

Volume group "vgdata" not found I tried multiple Live-CDs like gparted (with testdisk), Ultimate Boot-CD and SystemRescueCd, but none could help. Any idea what to do to get the lvm up and running? How to restore the metadata on hdc?
