resize server error

somebody help me :(

Hi,
I would suggest check your nova-compute logs for some error.
Also, you can check nova-scheduler logs to see if the VM was schedule to the compute node.
Can you ssh your machine?

Belmiro

thanks
i will checking now

this is the nova-scheduler.log when I execute resize command :

after that I checked with nova list and the status of the instance still ACTIVE not RESIZE

the log above is because I'm not adding :
  allow_resize_to_same_host=True
in nova.conf

after i tried to add :
  allow_resize_to_same_host=True
i got an error :

I found that in nova-compute.log

explain me that

ohhhhh thanks God

the FLAGS allow_resize_to_same_host=True is have to add to both nova.conf and nova-api.conf
in explain in http://docs.openstack.org/trunk/openstack-compute/admin/content/configuring-openstack-compute-basics.html
