I am using Spacewalk release 2.9 to manage my CentOS Linux server. using below spacecmd command to push the new packages. I want to reboot the server once all the packages are installed on the machine. I am unsure how to monitor package upgrade and issue the reboot command. Any recommendations to achieve this? I would like to use Ansible playbook to do this reboot.

spacecmd  system_upgradepackage  <hostname> '*' -y

Thanks SR

  • Above spacecmd command invokes the packages to be pushed, it won't wait until task completed, we need to wait patches pushed and reboot the server. – sfgroups Aug 22 at 15:34

Ansible can reboot the server without using spacecmd, using the reboot command.

- name: Upgrading via spacewalk
  shell: spacecmd  system_upgradepackage  <hostname> '*' -y
- name: Reboot after upgrades
  shell: reboot
  async: 0
  poll: 0
- name: Waiting for host to come up
  local_action: wait_for host={{ ansible_ssh_host }} state=started

  • we need to check patches pushed, before invoking os reboot. otherwise system will reboot in middle of patching. – sfgroups Aug 22 at 15:37

I'm not familiar with spacecmd, but you can use the wait_for module to monitor the PID.

From docs:

- name: Wait until the process is finished and PID was destroyed
  wait_for:
    path: /proc/3466/status
    state: absent
  • spacecmd will be running from control host, we can check the PID status to check the patch push status. – sfgroups Aug 26 at 14:13
  • so we can wait until the PID gets exited in localhost – msp9011 Aug 26 at 14:16
