Hi, I am trying to make a live migration of virtual machines (custom resource agent). The idea is to suspend the virtual machine on one node, remount a filesystem (on top of DRBD) on another node and resume the virtual machine. I have order constraints there to say that the virtual machine can only be run once the filesystem is mounted on the node. The problem is, however, that I can't live-migrate with such constraints:
notice: check_stack_element: Cannot migrate vcluster-vz1 due to dependency on drbd-r0-fs (order) If I understand correctly, pacemaker can not migrate a resource if it depends on some other resource. But is there any way to force other resources to move together with the migrating resource? In the worst case scenario I will try to have an additional parameter to my resource agent to force move the dependent resources... but I am looking for the right way to solve this problem, not some ugly hack. Any ideas?
