I am not able to start services for the following Centos 7 server

[root@myserver home]# uname -r
3.10.0-1160.11.1.el7.x86_64
[root@myserver home]# cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)

I first realised there was a problem when I observed that docker was down, so I ran the following as root

[root@myserver home]# systemctl start docker
 Authorization not available. Check if polkit service is running or see debug message for 
 more information.
 Failed to start docker.service: Connection timed out
 See system logs and 'systemctl status docker.service' for details.
[root@myserver home]# systemctl status docker.service
 ● docker.service - Docker Application Container Engine
 Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
 Active: inactive (dead)
 Docs: https://docs.docker.com

I then ran

 [root@myserver home]# systemctl | grep -i fail
 ● firewalld.service                          loaded failed     failed      firewalld - dynamic firewall daemon
 ● plymouth-start.service                     loaded failed     failed      Show Plymouth Boot Screen
 ● polkit.service                             loaded failed     failed      Authorization Manager
 ● systemd-machined.service                   loaded failed     failed      Virtual Machine and Container Registration Service
 ● tuned.service                              loaded failed     failed      Dynamic System Tuning Daemon

Also

 [root@myserver home]# systemctl status polkit.service
 ● polkit.service - Authorization Manager
    Loaded: loaded (/usr/lib/systemd/system/polkit.service; static; vendor preset: enabled)

  Feb 04 11:14:54 myserver.com systemd[1]: Unit polkit.service entered failed state.
  Feb 04 11:14:54 myserver.com systemd[1]: polkit.service failed.

I am not aware of any updates made to the server. I think these problems began after an unplanned reboot, but I can't establish the reason for the reboot. Why would starting the Authorization Manager time out? Does anyone have any suggestions for further investigation?

I issued a

[root@myserver home]# reboot

command and it seems to be working. Before, when I was having the initial problem, I had used

[root@myserver home]# shutdown -r now

I am curious as to why the difference in the two commands caused my initial problem...

Just document my case, this could help some one

polkit is a policy service that means some other services need it's authorization before executing actions

The problem appears after kvm backup restore guest VM uses centos 7 if I tried to start or restart any service like network or sshd the system reboots after showing this message for secons

Authorization not available. Check if polkit service is running or see debug message for more information.

In my case polkit was complaining about dbus error like

Failed to connect to system bus: Connection refused

journalctl -b -p err

I found that missing disk casus issues with dbus

Solution was easy remove the missing disk from fstab

Also I found similar problem here https://www.thegeekdiary.com/authorization-not-available-check-if-polkit-service-is-running-or-see-debug-message-for-more-information-centos-rhel-7-ssh-service-error/
