    Hi.

    I have a cPanel server running on CentOS7.
    When i run Security Advisor, i get the following message:
    Current kernel version does not match the kernel version for boot. running kernel: 3.10.0-327.36.3.el7.x86_64, boot kernel:Reboot the system in the "Graceful Server Reboot" area. Check the boot configuration in grub.conf if the new kernel is not loaded after a reboot.

    I have already performed a Graceful Server Reboot a couple of times with no success, i still get the message.

    I have also tried running yum-update but all packages are up to date.

    I noticed that you suggest checking the boot config in grub.conf - but after some Googling, i found out that no such file exists in CentOS7 (renamed and changed location) - im no expert on this area, this is why i need help.

    Hello,

    Could you verify the environment type and cPanel version for this server? You can check with these commands:

    Code:
    cat /var/cpanel/envtype
cat /usr/local/cpanel/version
    Also, let us know the output from:

    Code:
    rpm -qa|grep kernel
uname -r
    Thank you.

    Hi,

    I would like to add some more information to it. The server provider and the OS installed from their build also causes this issue where new kernel installation fails. Just check if the new kernel installation went well and that your grub.conf file has all the kernel listed in it that you are booting from.

    The OS is Centos 7

    The server provider is Velia.net . I have other dedicated cPanel servers hosted there, but never encountered this issue before.

    Hope this helps

    Hello,

    It looks like it was confirmed to be a false positive. We may have an internal case open to address this issue. Could you confirm if this system uses UEFI? You can check by verifying if the /boot/efi/EFI/centos/grub.cfg file exists:

    Code:
    ls /boot/efi/EFI/centos/grub.cfg
    Thank you.

    Hi, I seems to have the same problem, and it keeps coming up every time I do install cpanel/WHM on a Centos server both 6 or 7.

    cat /usr/local/cpanel/version => 11.64.0.36

    rpm -qa|grep kernel =>
    kernel-2.6.32-642.15.1.el6.x86_64
    kernel-2.6.32-696.299.3.2.cp6.x86_64
    dracut-kernel-004-409.el6_8.2.noarch
    kernel-firmware-2.6.32-696.299.3.2.cp6.x86_64
    kernel-2.6.32-642.el6.x86_64
    kernel-headers-2.6.32-696.299.3.2.cp6.x86_64
    kernel-2.6.32-696.6.3.el6.x86_64

    uname -r => 4.9.36-x86_64-linode85

    I've been trying to update kernel to no avail. Any help would be much appreciated.
    Thanks

    Hi,

    this has nothing to do with EFI, there is some other bug you have in there. For some reason you store information anywhere which kernel you expect and this is not handled correctly after a kernel update.
    As I updated from 3.10.0-514.2.2.el7.x86_64 to 3.10.0-514.26.2.el7.x86_64 I also get the message now
    Current kernel version does not match the kernel version for boot. running kernel: 3.10.0-514.26.2.el7.x86_64, boot kernel: 3.10.0-514.2.2.el7.x86_64
    Why do you expect the older ...514.2.2.... kernel to run?

    The 514.26 kernel is running smoothly and everything works like expected but WHM wants a server reboot which will never choose the 514.2.2 kernel as I updated the default to 514.26, so what to do about that? I have NO EFI boot

    [root@ms1 log]# cat /var/cpanel/envtype
    kvm
    [root@ms1 log]# cat /usr/local/cpanel/version
    11.64.0.36
    [root@ms1 log]# rpm -qa | grep kernel
    kernel-tools-3.10.0-514.26.2.el7.x86_64
    kernel-3.10.0-327.el7.x86_64
    kernel-3.10.0-514.2.2.el7.x86_64
    kernel-tools-libs-3.10.0-514.26.2.el7.x86_64
    kernel-3.10.0-514.26.2.el7.x86_64
    kernel-headers-3.10.0-514.26.2.el7.x86_64
    kernel-3.10.0-327.36.3.el7.x86_64

    So the question is where do you store the information which kernel YOU expect? Because this is senseless as I want to run the kernel I want to run...

    For all : Please check with
    grub2-editenv list
    if the actual kernel you want to run is set as default
    if not set the corresponding grub menuentry with grub2-set-default
    this removed the wrong error message for me.
    Somehow cPanel seems to check the running kernel against the default set one and is not updating this information correctly when installing a new kernel, so if you set a default entry on your own in /etc/default/grub without using saved in GRUB_DEFAULT and setting the correct one with grub2-set-default you get an error message

    Hello,

    Internal case CPANEL-14702 is open to address this particular issue. I'll monitor the case and update this thread with more information as it becomes available. In the meantime, the workaround is to manually set the latest kernel version using the "grub2-set-default" command and then run the "/scripts/rpmup" command. EX:

    Code:
    grub2-set-default $kernel-version
/scripts/rpmup
    Replace "$kernel-version" with the most recent kernel version that you booted the server into.

    Thank you.
