Step F: Complete the Downgrade on Node B
Perform these steps at node B. Remember that in Step D: Downgrade Node B, you were prompted either to reboot or to restart elemental_se. You now obey that prompt.
Enter this command to reboot:
[elemental@hostname ~]$
sudo rebootThe reboot takes approximately 5 minutes. When the reboot completes, the elemental _se service automatically starts. Look for this message on the command line:
Starting elemental_se: [ OK ]
If you didn't meet the conditions for special downgrade, skip this step.
If you met the conditions for special downgrade, run the installer with downgrade to your desired version.
[elemental@hostname ~]$ sudo sh ./elemental_production_delta_
<version>
.run –-skip-all –xeula --start --downgrade --restore-db<path/to/database/backup>
The new software is installed and all services except elemental_se are automatically restarted.
Once installation is complete, you might be prompted to reboot:
Installation and configuration complete! . . . NOTE: You must reboot your system to finish the installation!
Enter this command to reboot:
