Public bug reported: Description of problem: The migration and live migration of instances fail when Nova is set to work with RBD as a back end for the instances disks. When attempting to migrate an instance from one host to another an error prompt:
Error: Failed to launch instance "osp5": Please try again later [Error: Unexpected error while running command. Command: ssh <host address> mkdir -p /var/lib/nova/instances/98cc014a-0d6d-48bc-9d76-4fe361b67f3b Exit code: 1 Stdout: u'This account is currently not available.\n' Stderr: u'']. The log show: http://pastebin.test.redhat.com/267337 when attempting to run live migration this is the output: http://pastebin.test.redhat.com/267340 There's a work around, to change the nova user settings on all the compute nodes, on the /etc/passwd file from sbin/nologin to bin/bash and run the command. I wouldn't recommend it, it creates a security breach IMO. Version-Release number of selected component (if applicable): openstack-nova-api-2014.2.2-2.el7ost.noarch python-nova-2014.2.2-2.el7ost.noarch openstack-nova-compute-2014.2.2-2.el7ost.noarch openstack-nova-common-2014.2.2-2.el7ost.noarch openstack-nova-scheduler-2014.2.2-2.el7ost.noarch python-novaclient-2.20.0-1.el7ost.noarch openstack-nova-conductor-2014.2.2-2.el7ost.noarch How reproducible: 100% Steps to Reproduce: 1. Set the nova to work with RBD as the back end of the instances disks, according to the Ceph documentation 2. Launch an instance 3. migrate the instance to a different host Actual results: The migration fails and the instance status moves to error.
