Hi, I'm try to setup a two node cluster for virtuell machines (KVM/libvirt) with drbd as storage backend. For each vm I use two drbd devices. Starting and stopping works but I cant migrate the VM to the second node. If i switch a node to "standby" the VM stays "started" and there ist no call to VirtualDomain.
I found the following in this list [0] "Yes, migration only works without order-contraints the migrating service depends on ... and no way to force it" and I use order constraints because I need the drbd devices up before the vm starts. How do I migrate a vm or other ressources in the correct order? Is there another way to migrate vm and drbd device, maybe start/stop? My current config looks like this: primitive vma_R ocf:linbit:drbd params drbd_resource="vma_R" \ op monitor interval="29s" role="Master" \ op monitor interval="31s" role="Slave" \ op start timeout="240s" \ op stop timeout="100s" ms ms_vma_R vma_R \ meta master-max="1" master-node-max="1" \ clone-max="2" clone-node-max="1" \ notify="true" primitive vma_S ocf:linbit:drbd params drbd_resource="vma_S" \ op monitor interval="29s" role="Master" \ op monitor interval="31s" role="Slave" \ op start timeout="240s" \ op stop timeout="100s" ms ms_vma_S vma_S \ meta master-max="1" master-node-max="1" \ clone-max="2" clone-node-max="1" \ notify="true" primitive kvm_vma ocf:heartbeat:VirtualDomain \ params config="/etc/libvirt/qemu/vma.xml" \ hypervisor="qemu:///system" migration_transport="ssh" \ meta allow-migrate="true" \ op start timeout="120s" \ op stop timeout="180s" \ op monitor depth="0" timeout="30" interval="10" colocation vma_on_drbd \ inf: ms_vma_R:Master ms_vma_S:Master kvm_vma:started order vma_after_drbd \ inf: ms_vma_S:promote ms_vma_R:promote kvm_vma Thanks Matthias [0] http://www.mail-archive.com/pacemaker@oss.clusterlabs.org/msg10499.html _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
