Hi, I am running nova-compute 2013.1.3-0ubuntu1~cloud0 on ubuntu precise
I am trying to migrate 1 instances from 1 compute node to another using the command: *nova live-migration --block_migrate 08893517-ceee-4b59-aee5-1aa568de3491 compute1* * * I get the following error in nova-compute log: 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp Traceback (most recent call last): 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/amqp.py", line 430, in _process_data 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp rval = self.proxy.dispatch(ctxt, version, method, **args) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/openstack/common/rpc/dispatcher.py", line 133, in dispatch 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp return getattr(proxyobj, method)(ctxt, **kwargs) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/exception.py", line 117, in wrapped 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp temp_level, payload) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/contextlib.py", line 24, in __exit__ 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp self.gen.next() 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/exception.py", line 94, in wrapped 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp return f(self, context, *args, **kw) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 3140, in check_can_live_migrate_source 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp dest_check_data) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/driver.py", line 2912, in check_can_live_migrate_source 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp dest_check_data['disk_over_commit']) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/driver.py", line 2964, in _assert_dest_node_has_enough_disk 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp raise exception.MigrationPreCheckError(reason=reason % locals()) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp MigrationPreCheckError: Migration pre-check error: Unable to migrate 08893517-ceee-4b59-aee5-1aa568de3491: Disk of instance is too large(available on destination host:-37580963840 < need:41126400) 2013-10-30 17:09:51.003 1970 TRACE nova.openstack.common.rpc.amqp 2013-10-30 17:09:51.004 ERROR nova.openstack.common.rpc.common [req-d2bd03ef-32d9-42eb-9711-e75a1b38b14f 256c891b6fcb4cdea0ab837a36da03de cd67bb936ef94f849188c406a11a59ae] Returning exception Migration pre-check error: Unable to migrate 08893517-ceee-4b59-aee5-1aa568de3491: *Disk of instance is too large(available on destination host:-37580963840 < need:41126400) to caller* It seems to be reporting the destination host has -minus storage - im i reading that correct? - im trying to migrate the cirros image which is only 40M in size Nova Database in table compute_nodes reports my compute node has: free local_gb: 699 free_disk_gb: 329 This free space is also reporting in the nova-compute logs during the audit 2013-10-30 17:15:33.016 26203 AUDIT nova.compute.resource_tracker [-] Free disk (GB): 329 Any ideas.
