Home > Balancer  > Correcting the duplicate Balancer process issue

Certain clients with specific configurations and versions have had an issue where duplicate Balancer/HAProxy processes are causing a split-brain type of operation after reloads. Historically the fix has been stopping and starting the Balancer to clear it out, however, there is a patch available for the problem.

Important! Only apply this is you are running either Snapt_Leap_v11.x86_64-2.0.1 or Snapt_v13.x86_64-1.0.4. 

You can check your version by running the following command:

cat /etc/os-release|grep PRETTY_NAME

You should see exactly this string: PRETTY_NAME=”openSUSE Leap 42.1 (x86_64)”

If you do you can now continue. Ensure you take a backup of your entire VM before running any patches!



Step 1: Stop the Balancer

Ensure that you have stopped the Balancer completely in the UI, and if you are using redundancy monitored applications, remove it from there before stopping.

Step 2: Download and install the patch

/etc/init.d/haproxy stop; service haproxy stop; killall -9 haproxy
/bin/rpm -i --replacepkgs --replacefiles snapt-ha-1.7.8-1.1.x86_64.rpm

Step 3: Start the Balancer

You may now start the Balancer again. Check everything is working correctly and test a reload.
