Fix initramfs from broken update

Fix initramfs from broken update

Overview

I updated my CentOS 7 virtual guest and after boot it could not locate my partitions. I had actually 2 instances, an LVM guest and a non-LVM guest. LVM guest waited for a few minutes until it told me some errors about dracut. Non-LVM guest waited indefinitely for vda partition mount.

In practice you may see this kind of error message:

dracut-initqueue timeout

And in detail i just got this on my screen :)

dracut-initqueue[247]: Warning: dracut-initqueue timeout - starting timeout scripts

and get thrown into dracut shell.

Solution

I booted the virtual instance with CentOS 7 ISO, selected rescue mode, let it mount existing system as read-write to /mnt/sysimage and chrooted to it.

While chrooted I rebuilt my initramfs with following command:

dracut -H -f /boot/initramfs-3.10.0-1127.8.2.el7.x86_64.img 3.10.0-1127.8.2.el7.x86_64 || dracut -fv --regenerate-all

Where 3.10.0-1127.8.2.el7.x86_64 is the kernel version, which you must check before issuing the command. Using uname is not recommended as you are doing this with a rescue kernel.

After that just sync and reboot. You may need to reboot twice.

This worked thanks! It just rebuilt something in the boot and rebooted itself first.
