Like my previous blog entry I will endeavour explain how to recover from master failure but this time with version 5.10. (NOTE: once again this will only work with a simple configuration anything more complicated than simple direct routing its best to contact support@loadbalancer.org)
Hopefully you have your backup files – getharesources.php, getloadbalancercf.php and getrealip.php.
As a new member of the Loadbalancer team, I have been given the unenviable task of explaining how to recover your cluster should your master fail, (Note: fail as in hardware failure not just unplugging the network cable!)
Hopefully you have handy the backup configuration file – lb_config.xml
If you don’t have a copy already and your looking at this article because your organised and planning for disaster, NOW might be a good time to go and get one.
Log into your master Loadbalancer and select “Maintenance” and click on “Disaster Recovery” then “Download XML Configuration file” and keep the file that is downloaded somewhere safe. (more…)
