Hi, I'm trying to understand a strange behaviou, maybe someon here can help me out.
I configured 3 VMs primitives in my pacemaker cluster. Migrating a VM
works fine.
But when I tell pacemaker to move one VM away, all the VMs are migrating
to another node, together. This is not load balancing as I planned to
implement it :)
See my configuration at end of this message.
