Fix initramfs from broken update


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.


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.


All comments and corrections are welcome.

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