I have a disk with the following structure on fdisk -l command
Device Boot Start End Blocks Id System
/dev/xvdh1 * 2048 2099199 1048576 83 Linux
/dev/xvdh2 2099200 16777215 7339008 8e Linux LVM
(the disk is attached to another running centos 7 vm, hence you are seeing xvdh1 & 2, else they will be xvda1&2 for the vm 'will be running)
as you can see xvdh1 is the boot ; contains only the replica of boot directory in xvdh2 while xvdh2 is the one that has all --> /boot /root /etc /shm ...
I am getting dracut error
204.955113] dracut-initqueue[669]: Warning: dracut-initqueue timeout - starting timeout scripts

You might want to save "/run/initramfs/rdsosreport.txt to a USB stick or /boot
after mounting them and attach it to a bug report.
Any ideas on getting this right? much appreciated.
PS: I chrooted to dir that mounted xvdh2 and ran dracut -f ; generated intramfs... img but still running into same dracut error.
Thanks in advance!

Re: dracut and centos 7
There should be nothing in the /boot directory on the 2nd partition, it should be empty. You need to mount the 1st partition on the 2nd partition's /boot before you chroot and run dracut. You probably also need to specify the kernel version that you want it to build the initramfs for or else it will use the running one from the booted machine.
The future appears to be RHEL or Debian. I think I'm going Debian.

Re: dracut and centos 7
Thanks for your response and direction. I tried that;
1. Emptied xvdh2 boot dir
2. mounted xvdh1 on the boot dir
3. chrooted
4. issued dracut -f --kver kernel-version_i_have in the xvdh1
Had several warnings that some libraries missing..
5. Dracut completed
6. Shutdown -h now
removed/detached the disk and tried booting with another vm
same dracut timeout and unable to find root and boot
The etc/fstab has the following entries
/dev/mapper/centos-root / xfs defaults 0 0
UUID=a7bc7c98-bfaa-430c-91e8-89c160cd6097 /boot xfs defaults 0 0
/dev/mapper/centos-swap swap swap defaults 0 0
Anything else I need to do here? Pls note that this is a remote vm ; I do not have access to the console
Many thanks in advance!!

Re: dracut and centos 7
I am now tired of multiple images and several variations
I get below. Is this a bug or something? what can I do? I basically import centos 7 image into aws
and it bombs this way. Please can someone point me in the right direction? Thanks a million in advance.

Re: dracut and centos 7
Can you do the following:
1. Mount the root from xvdh2 on /mnt
2. mount /proc, /sys, /dev , /tmp and /run under /mnt with the option rbind '-o rbind'
For example ' mount -o rbind /proc /mnt/proc'
3. Mount xvdh1 on /mnt/boot
4. chroot /mnt
5. List the /boot once you chroot
6. Run 'pvs;vgs;lvs'
7. Run ' dracut -f --regenerate-all' or only specific version
8. Umount all 'umount -R /mnt ; umount /mnt'
Once you triy to boot, report what if it works or if any error is detected.

Re: dracut and centos 7
Many thanks to all!! At last 'got it working,
Culprit was the grub entry which pointed both kernel and intrafms in a different directory
did blkid , crosscheked with fstab mounts and figured that grub entries are mismatched.
nevertheless, the knowledge that you have shared with me is price less. Big thank you!

Re: dracut and centos 7
Hi!
I am facing same issue with centos 7.6. However in my case dracut file is all correct and intact. When the scenario is tested multiple times with the same disk, sometimes it fails to identify the root volume.
The observation is, whenever it goes in dracut emergency mode while finding the root disk, actually all LVM related files are missing from initramfs image.
So here are the steps.
1. Updated dracut.conf with required additional driver.
2. Created new image with dracut -f <image file> <kernel version>
Image gets successfully created.
Crass verified required driver entries using lsinitrd.
On Failure
#lsinitrd initramfs-3.10.0-123.el7.x86_64.img.bkp | grep lvm returns nothing.
On Success
# lsinitrd initramfs-3.10.0-123.el7.x86_64.img | grep lvm

Any guess why dracut is failing to inject lvm related packages? and this happens once in 5 iterations.
Your help is really appreciated.
Thanks!

Re: dracut and centos 7
If you have a kernel version of 3.10.0-123 then you are not running CentOS 7.6. That is 7.0 and thus you have 5.5 years worth of bugs and security vulnerabilities present on your system.
Run yum update to get up to date and reboot into the 3.10.0-957.5.1.el7 kernel.
Run yum update to get up to date and reboot into the 3.10.0-957.5.1.el7 kernel.
The future appears to be RHEL or Debian. I think I'm going Debian.
