    And the server doesn't reboot at all.

    Same issue even with different command:
    • systemctl reboot
    • reboot

    Maybe related to CentOS 7 fix update for Polkit ? https://rhn.redhat.com/errata/RHBA-2017-0392.html

    tried a hard reboot via OVH control panel ?

    Yes, that works but will take almost 10 minutes.
    Then reboot via cli still the same problem.

    Using fresh CentOS7.3 install.

    Just an update, It works fine with CentOS6.8.
    So the problem relies behind CentOS7.3 OS and OVH Server.

    what you doing from initial Centmin Mod install leading up to server reboot ? or is this problem happening without Centmin Mod install and just first CentOS 7.3 login on fresh install ?

    Tried CentOS 7.3 fresh install and yum update and reboot without install Centmin Mod ?

    Also check your dmesg logs in /var/log for clues. See 7 'dmesg' Commands for Troubleshooting and Collecting Information of Linux Systems

    On CentOS 7 can also be inspected for dmesg via journalctl kernel flag

    I filter out Firewall: related entries for today only
    Code (Text):
    journalctl -k --no-pager --since "today" | grep -v 'Firewall:'
    


    and boot log on CentOS 7
    Code (Text):
    journalctl -b --no-pager | grep -v 'Firewall:'
    


    Be care not to post these logs publicly as they can contain sensitive info, ips, ssh port numbers etc.

    Yes.

    Edit for this, not having the same error on CentOS 7, But the server didn't reboot again.

    Yes I tried that.
    Same issue.

    Now I will try again using their own kernel.

    Sounds like a probably specific to your OVH server then !

    I just re-install the server again:

    - Install from an OVH template
    - Type of operating system = CentOS 7.3-1611 - centos7
    - Default partition configuration
    - Set hostname
    - All 8 stages of installation done quick except for "Rebooting under fresh system ( 5 / 8 )" which consumes 5 minutes.
    - that it's unusual for me as I have plenty of OVH Server already which get's re-installed in a few minutes only.
    - Done Installation.

    - ssh to the server again
    - then reboot it for the first time via command "reboot", it doesn't have the old error now.
    - BUT, But the server didn't reboot again.

    I'm confuse now what to do.
