The LVM volume is wiped using dd, but it is not disconnected from qemu-nbd before the LVM volume gets removed. The instance in itself on the compute node is stopped but still marked as Active, Deleting in nova. qemu-nbd is sill running. After first failure, disconnecting the qemu-nbd process manually and relaunching the instance termination works Log file in debug attached Environment: Ubuntu 12.04 OpenStack grizzly Configuration for LVM: libvirt_images_type=lvm libvirt_images_volume_group=nova_local Error: (The full stack can be find in attached log) 2013-04-25 12:02:59.119 10796 TRACE nova.openstack.common.rpc.amqp ProcessExecutionError: Unexpected error while running command. 2013-04-25 12:02:59.119 10796 TRACE nova.openstack.common.rpc.amqp Command: sudo nova-rootwrap /etc/nova/rootwrap.conf lvremove -f /dev/nova_local/instance-00000004_disk 2013-04-25 12:02:59.119 10796 TRACE nova.openstack.common.rpc.amqp Exit code: 5 2013-04-25 12:02:59.119 10796 TRACE nova.openstack.common.rpc.amqp Stdout: '' 2013-04-25 12:02:59.119 10796 TRACE nova.openstack.common.rpc.amqp Stderr: ' Can\'t remove open logical volume "instance-00000004_disk"\n' To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1172691/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
