“You can test a real world crash that requires fencing by killing the proccess called ‘cib’ on the standby node. A command such as ‘killall cib’ should immediately trigger a fence event, and will allow you to validate your fencing configuration.”
And it killed both boxes instead of only one. I’m using IPMI. Obviously, it’s working for both, a little too well it seems. Can anyone help with this?
I must admit although I using the HA module, and its working very well, I still have not enabled fencing. I was worried about things like this happening. I have had split brain problems a couple off time so will enable fencing once I’m happy everything is stable. I do get problems with our overnight backups freezing the severs briefly and the HA stuff trying to failover etc.
I can say that when we did have a major problem in one of our server rooms, the FreePBX HA failed over perfectly, and very useful feature.
Using Distro 6.6 and FreePBX 13 and I am unable to test fencing, when I kill the cib process it gets restarted intermediately so nothing happens… I’m guessing HA has been improved to be more resilient to crashes of the cib process?
