Yes, copy it to a new name, and edit that.

Unfortunately, migration is not live migration ... a resource (the VM) can't be live-migrated if it depends on another resource (the IP) that isn't live-migrateable. If you modify IPaddr to be live-migrateable, it should work. It has to support migrate_from and migrate_to actions, and advertise them in the meta-data. It doesn't necessarily have to do anything different from stop/start, as long as that meets your needs. >>> What i found in the net: >>> http://lists.clusterlabs.org/pipermail/pacemaker/2011-November/012088.html >>> >>> " Yes, migration only works without order-contraints the migrating service >>> depends on ... and no way to force it." >> >> I believe this was true in pacemaker 1.1.11 and earlier. >> > > Then it should be possible: > > ha-idg-2:~ # rpm -q pacemaker > pacemaker-1.1.12-11.12 > > Bernd > > > Helmholtz Zentrum Muenchen > Deutsches Forschungszentrum fuer Gesundheit und Umwelt (GmbH) > Ingolstaedter Landstr. 1 > 85764 Neuherberg > www.helmholtz-muenchen.de > Aufsichtsratsvorsitzende: MinDir'in Baerbel Brumme-Bothe > Geschaeftsfuehrer: Prof. Dr. Guenther Wess, Heinrich Bassler, Dr. Alfons > Enhsen > Registergericht: Amtsgericht Muenchen HRB 6466 > USt-IdNr: DE 129521671 > ___ Users mailing list: Users@clusterlabs.org http://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org

[ClusterLabs] can't live migrate VirtualDomain which is part of a group
Hi, i have a primitive VirtualDomain resource which i can live migrate without any problem. Additionally i have an IP as a resource which i can live mirgate easily too. If i combine them in a group, i can't live migrate the VirtualDomain anymore. It is shuted down on one node and rebooted on the other. :-( This is my config: primitive prim_vm_mausdb VirtualDomain \ params config="/var/lib/libvirt/images/xml/mausdb_vm.xml" \ params hypervisor="qemu:///system" \ params migration_transport=ssh \ params autoset_utilization_cpu=false \ params autoset_utilization_hv_memory=false \ op start interval=0 timeout=120 \ op stop interval=0 timeout=130 \ op monitor interval=30 timeout=30 \ op migrate_from interval=0 timeout=180 \ op migrate_to interval=0 timeout=190 \ meta allow-migrate=true is-managed=true \ utilization cpu=4 hv_memory=8005 primitive prim_vnc_ip_mausdb IPaddr \ params ip=146.107.235.161 nic=br0 cidr_netmask=24 \ meta is-managed=true group group_vnc_vm_mausdb prim_vnc_ip_mausdb prim_vm_mausdb \ meta target-role=Started Why can't i live migrate the VirtualDomain primitive being part of a group ?
