Hi,
Nova provides a flag ‘allow_resize_to_same_host’ to resize the given
instance on the same hypervisor where it is currently residing. When
this flag is set to True, the nova.compute.api: resize() method does not
set the scheduler hint with ‘force_nodes’, where as its set the
‘ignored_hosts’ properly when this flag is set to False.
So I have filed following defect to fix the logic when this flag is set
to True.
https://bugs.launchpad.net/nova/+bug/1356309
I felt this defect is import to fix, when cloud admin wants the resize
to be happen on the same hypervisor (compute node). So could you please
let me know whether I can fix this for Juno-3? Thanks.
Hi Kanagaraj,
AFAICT, there is no bug here.
if not CONF.allow_resize_to_same_host:
filter_properties['ignore_hosts'].append(instance['host'])
else:
filter_properties['force_nodes'] = [instance['node']]
When allow_resize_to_same_host is True, then
filter_properties['force_node'] will be set to a list with only one node
(the compute node that the instance is currently on), and therefore the
resize will happen on the original host.
Best,
-jay
