dracut error after upgrading Mageia 3 to 4

[dandys997]

Hi,
yesterday I've upgraged my Mageia 3 to Mageia 4 using mgaonline. There was about 2,5k packages and everything finished well.

However, after reboot my Mageia doesn't start. I get the message:

dracut Warning: Could not boot.
dracut Warning: /dev/non-hostonly-lvm does not exist

Generating "/run/initramfs/rdsosreport.txt"
You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick after mounting them and attach it to a bug report.

To got more debug information in the report,
reboot with "rd.debug" added to the kernel command line.

Dropping to debug shell.

dracut:/#

What's wrong with it? How can I fix it?

Thanks in advance for help.

Maybe your systems initrd does not include drivers to detect and use the LVM. In this case you may start a rescue DVD, switch to a terminal and do the following:

Code: Select all

# cd /mnt
# chroot /mnt
# cd /boot
# lsinitrd | grep lvm

If you do not get any results displayed you could create a new initrd with additional LVM drivers. Be careful to select the appropriate kernel version!

Code: Select all

# dracut --add-drivers "lvm" initrd-3.14.18-server-3.mga4.img 3.14.18-server-3.mga4

Try to reboot the system.
