Hi everybody,
I have a pacemaker + corosync cluster that manages a virtual machine (kvm) the virtual machine drives are stored in a shared storage (gfs2 + lvm+ iscsi LUN). The resource agent is VirtualDomain.
When I test the live migration with a command 'pcs resource move vmcentos2 nodo2' or putting the node on standby, the migration works with no problem.
But when I want to test the live migration rebooting or shutting down the node that runs the virtual machine, migration fails. Is this a expected behaviour or a bug?
My cluster configuration is:
OS=Centos 7 Pacemaker 1.1.10-32.el7_0.1Corosync Cluster Engine, version '2.3.3'
