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
wget https://shop.snapt.net/clientdata/snapt-ha-1.7.8-1.1.x86_64.rpm /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.
