Public bug reported: When you attempt to 'nova volume-update' a stopped instance, the block device mapping connection_info is corrupted (it points to the new volume despite the failure).
1. create an instance (instance-1) 2. create two volumes (vol-1 & vol-2) 3. attach volume: nova volume-attach instance-1 <vol-1-uuid> 4. nova stop instance-1 5. swap volume: nova volume-update instance-1 <vol-1-uuid> <vol-2-uuid> 6. swap will fail, but the connection info points to vol-2 now Example notes using stable/newton devstack: http://paste.openstack.org/show/586715/ A similar downstream bug report: Can't re-start a stopped instance after trying to volume-update on it https://bugzilla.redhat.com/show_bug.cgi?id=1373318 ** Affects: nova Importance: Undecided Assignee: Diana Clarke (diana-clarke) Status: New ** Changed in: nova Assignee: (unassigned) => Diana Clarke (diana-clarke) -- You received this bug notification because you are a member of Yahoo!
