Repair the LVM filter in /etc/lvm/lvm.conf to ensure it accepts the device associated with the root filesystem.
Ensure that the root VG and LV paths references in the GRUB configuration are correct.
The following steps offer one approach to troubleshooting and resolving this, making use of the dracut shell:

Code:
fdisk -l /path/to/image
it will show you the block-size and the start-block of the partition. You can use that to calculate the offset.
For example, I have an image of a bootable stick with a 4GB FAT32 partition. The output of the Read more...
