According to https://access.redhat.com/solutions/2515741

This happens if it can't find a logical volume:  "A logical volume cannot be found on the system"

1) does this happen every time you reboot?
2) does it print more if you wait?  Specifically, something like this after the "Could not boot"
[  200.161146]  dracut-initqueue[779]: Warning: /dev/vgroot/root does not exist
[  200.170895]  systemd[1]: Starting Dracut Emergency Shell...

3) Have you tried redeploying in ec2 again (maybe there was a problem importing into ec2?)

Comment 3 Joe Rafaniello 2018-05-02 18:28:53 UTC
Note, I don't believe we changed our kickstarts for generating the logical volumes in a long time.

Does this happen with all 5.9 versions?
Does it happen with 5.8?

Comment 4 Matouš Mojžíš 2018-05-03 13:52:43 UTC

1) Yes
2) It does, but I don't have access to logs in EC2 except latest screenshot of instance logs.
3) Yes, I tried it in different region. Same issue.

I test deployment of most of the versions and the latest I tested - and are working correctly.

Comment 7 Joe Rafaniello 2018-05-03 14:37:52 UTC
Matous, are the successful deployments to the same environment? What about the failures?  Is there anything common when it works vs when it doesn't?  Perhaps there's an environmental problem causing the inability to find the logical volumes.

Comment 8 Matouš Mojžíš 2018-05-03 15:02:06 UTC

successful deployments are to the same environment.
The only common thing is deploying Other versions work correctly.

Comment 9 Joe Rafaniello 2018-05-03 15:12:32 UTC
Matous, how many deployments did you do and how many failed in this way?

Did any other version fail in this way in the same environment?

Comment 10 Matouš Mojžíš 2018-05-03 15:14:45 UTC

I tried to deploy four times. It failed every time. I also tried to reimport image to ec2. Still didn't work.

Any other versions are working correctly in this way in same environment.
I test the image with exactly same steps for every version.

Comment 11 Joe Rafaniello 2018-05-03 15:52:49 UTC
Matous, can you try the steps here:  https://access.redhat.com/solutions/2515741 ?

Note, there are comments at the bottom with some useful information.

In a private comment, can you share the ip/credentials of a  I'd like to compare the rpm package list with one that Satoe did with  Maybe the kernel or something in the OS is different?

Comment 13 Joe Rafaniello 2018-05-03 17:41:15 UTC
The differences in rpms from (working for Matous) to (working for Satoe, not working for Matous):

Comment 14 Matouš Mojžíš 2018-05-04 15:20:40 UTC
I have found what's wrong. image doesn't allow me to use c5.xlarge so I used for it c4.xlarge instance. allows me to ues c5.xlarge instance and image is broken for this instance type.
When I run image on c4.xlarge then it works correctly.
Difference between c4 and c5 is newer processors and added ENA support.

Comment 16 Joe Rafaniello 2018-05-04 15:52:36 UTC
Wow, nice find Matous.

From above link (credit to hhsnow user):

  If you're rolling your own CentOS 7 AMI and are encountering issues booting it on the c5's (but works with other instance families), try running these two before taking the AMI:

  yum install dracut-config-generic
  dracut -f

  From AWS support:
  In order to have the correct initramfs to be created with your script I had to install a package named "dracut-config-generic". This package provides the configuration to turn off the host specific initramfs generation with dracut and generates a generic image by default. This package includes a single configuration file for dracut:

  | $ cat /usr/lib/dracut/dracut.conf.d/02-generic-image.conf
  | hostonly="no"

  After I installed this package and rebuild the initramfs with "dracut -f" it started to boot normally on C5s. You can note the size difference between the initramfs files:

  * Before the installation of "dracut-config-generic":
  -rw------- 1 root root 19719505 Nov 13 16:28 initramfs-3.10.0-693.5.2.el7.x86_64.img

  * After the installation of "dracut-config-generic":
  -rw------- 1 root root 46942834 Nov 15 01:01 initramfs-3.10.0-693.5.2.el7.x86_64.img

Also, for hhsnow user:

  Is ENA enabled for your instance? Via command line: 
  aws ec2 describe-instances --instance-ids {instance_id} --query 'Reservations[].Instances[].EnaSupport'

  If not (stop instance and):
  aws ec2 modify-instance-attribute --instance-id {instance_id} --ena-support

  To make the AMI automatically support ENA, you need to enable ENA on the instance before you create the image."

Comment 17 Joe Rafaniello 2018-07-23 13:54:34 UTC
Hi Matouš,

I haven't heard reply back on this bug.  Is this still an issue?  Did my links provide any help?  This is still marked urgent, can it be lowered or closed?

Comment 18 Joe Rafaniello 2018-07-31 16:57:51 UTC
Closing for now, please reopen if this is still a problem and you find out what we're doing wrong for this platform.  I'm not sure what actions we need to do to fix this.

Comment 19 Matouš Mojžíš 2018-08-01 15:09:59 UTC
Hi Joe,

I had some issues installing and running ENA drivers for this image so that's why it took me so long.

I was able to install on CFME 5.10 image ENA drivers with this tutorial:

also I did after installing drivers this:
  yum install dracut-config-generic
  dracut -f

then c5 instance types started working for this image.
I think we should distribute cfme image for amazon with these ENA drivers.

So setting back to ASSIGNED and lowering severity.

Comment 20 Joe Rafaniello 2018-08-06 14:10:58 UTC

Can you review comment #19?  I don't know if these amazon drivers are already packaged or if we would need to create rpms for them and if we can redistribute them.  I didn't look to see if there were additional build packages needed to do this.

If this is something you think you can work on, we can reassign.  If this needs prioritization, we can have others review the need for this enhancement/bug fix.

For now, it can stay in my queue until we know what we can and will do.


Comment 21 Satoe Imaishi 2018-08-17 21:44:31 UTC
ENA driver should be already included in RHEL, so I'm not sure why the driver needs to be added. I'll have to do some research and test, to figure out exactly what's needed.

Just as a data point, I was also having this issue on the t3 instance types. It boots just fine on the t2 instances though.

Comment 25 Matouš Mojžíš 2018-09-17 13:51:44 UTC
Verified in CFME appliance is booting in EC2 environments with newer instance types - tried c5, c5d. 
There are also different changes in these instance types like disk naming - https://bugzilla.redhat.com/show_bug.cgi?id=1629853
