Open Stack

Hi Melvin,
   Thanks for the reply.
I tried the CLI command using debug option and found the version used for each module.
compute API version 2, cmd group openstack.compute.v2
network API version 2, cmd group openstack.network.v2
image API version 2, cmd group openstack.image.v2
volume API version 2, cmd group openstack.volume.v2
identity API version 3, cmd group openstack.identity.v3
object_store API version 1, cmd group openstack.object_store.v1
neutronclient API version 2, cmd group openstack.neutronclient.v2
dns API version 2, cmd group openstack.dns.v2
orchestration API version 1, cmd group openstack.orchestration.v1
data_processing API version 1.1, cmd group openstack.data_processing.v1
workflow_engine API version 2, cmd group openstack.workflow_engine.v2
database API version 1, cmd group openstack.database.v1

some of the API call were version 2.1
GET call to compute for http://10.106.138.21:8774/v2.1/49d9e9912971479f833ba6f947646b53/servers/vm5
“openstack server dump create” is not supported in API version 2.0
I followed openstack installation guide for packstack ocata .
By default the nova API version 2.0 used for all operation.
It means the command not supported in ocata version?
Please correct me if I am wrong.

Is there any way to change the API version in packstack?
Attaching the full log in the mail.


Regards,
Bala

Hi Bala,

I do not have an environment to test my theory on but I believe the openstack client is not setting appropriate version. Try running 'openstack --debug server dump create vm2' and look for the request URI to see if the version is set to 2.1 or higher. A quick glimpse at the code and the nova client itself, I believe openstack client attempt to use API version '2.0' as outlined in your error message is the problem. Hope this helps.

Hi All,
   I am trying to create dump file for instance created on openstack.
But unable to create a dump. Particular CLI commands throwing below error.

[root at control-packstack ~(keystone_admin)]# openstack server dump create vm2
API version '2.0' is not supported on 'novaclient.v2.servers.[class ServerManager(base.BootingManagerWithFind):].trigger_crash_dump' method.

Can anyone help me to fix this issue.
Do I need to upgrade  novaclient or openstack python client?
My openstack version is Ocata and am using openstack with opendaylight controller.

Regards,
Bala
