FC8: "no Volumegroups found" after Mainboard-Change, Rescueboot:OK
After changing the mainboard, booting of several preexistent FC8-Installations fails: "No volume groups found". (kernel can not mount root-filesystem.)
DVD-Rescue-Boot however is OK, volumegroups are found and root-filesystem is accessible.
I've been searching quite a while for a solution.
Any help would be great! Thanks.

Have you tried to rebuild your initrd from the rescue environment? It's possible that the new motherboard requires a different set of kernel modules to boot than the old one.
Regards,
Bryn.

I've run into this several times. In my cases, the problem has been a change in disk controller, so that the drivers in initrd no longer work. This can usually be fixed by booting the rescue, mount the root and boot, chroot, and mkinitrd. You might need to use lsmod to find out which driver is needed if mkinitrd can't figure it out from the chroot environment. Use -v to make sure mkinitrd is including the LVM stuff. If not, more manual overrides are in order.
