Description of problem: When attempting to migrate (live) a vm cluster resource from one node to another in the cluster using "clusvcadm -M <svc_name> -m <member>", the operation fails with the following error messages: Trying to migrate service:svc1 to node2...S/Lang Script Error In /var/log/messages: Aug 14 16:44:08 node2 rgmanager[3210]: [S/Lang] Variable Uninitialized Error Aug 14 16:44:08 node2 rgmanager[3210]: [S/Lang] Script Execution Failure According to Lon Hohberger (lhh), this represents a known issue: <quote from="linux-cluster"> You can't mix central_processing + migrate operation right now. The central_processing mode _requires_ synchronous operation, but with the older (Xen) tools, the man page explicitly documents that most operations were asynchronous - consequently, 'xm migrate' may or may not have completed at the time the command returned. With current virsh agent, we can fix this behavior because the virsh operations (including migrate) are expected to be synchronous. I talked with the libvirt developers about this recently - the fact that virsh operations are synchronous (despite also being documented to be asynchronous [GRRRRR] in the virsh man page) -greatly- simplifies the steps we must take surrounding VM migration, so we can fix it now that we use virsh instead of 'xm' </quote> Version-Release number of selected component (if applicable): cman-3.0.0-20.fc11.x86_64 rgmanager-3.0.0-20.fc11.x86_64 resource-agents-3.0.0-12.fc11.noarch How reproducible: All the time -> see above quote. Steps to Reproduce: 1. Configure cluster.conf with a vm resource using virsh and with central_processing turned on for the resource manager. e.g: <rm log_level="7" central_processing="1"> and <vm name="kvm02" migrate="live" snapshot="/cluster/kvm-guests/snapshots" use_virsh="1" hypervisor="qemu"> 2. clusvcadm -M kvm02 -m <node> Actual results: Trying to migrate service:svc1 to node2...S/Lang Script Error In /var/log/messages: Aug 14 16:44:08 node2 rgmanager[3210]: [S/Lang] Variable Uninitialized Error Aug 14 16:44:08 node2 rgmanager[3210]: [S/Lang] Script Execution Failure Expected results: That the service is live-migrated to the other node w/o failure.
