Icehouse Cluster mode Driver can't create Volume (No valid host was found)

Icehouse Cluster mode Driver can't create Volume (No valid host was found)

The cinder.conf file is the following:

[DEFAULT]

enabled_backends=iscsi_emc_vmax_1,3250direct1

...

[3250direct1]

volume_backend_name=3250direct1

volume_driver=cinder.volume.drivers.netapp.common.NetAppDriver

netapp_server_hostname=xx.xx.xx.xx -> cluster mgmt ip addr

netapp_server_port=80

netapp_storage_protocol=iscsi

netapp_storage_family=ontap_cluster

netapp_login=admin    

netapp_password=xxxxxx

netapp_vserver=openstackVS1

When i try to create a volume on backend named "3250direct1", i received the following error message on cinder-scheduler.log file:

The command issued to create the volume is "cinder create --volume-type 3250direct1 --display-name test 1"

...

2014-06-06 11:55:24.481 24590 ERROR cinder.scheduler.flows.create_volume [req-52c129c0-8f1c-468e-9566-8ef287b3e31b 912af7e8976448df80894348d8158d39 3ab47e19d21c4672973e57e7a8c85c83 - - -] Failed to schedule_create_volume: No valid host was found.

...

Also I noticed that when trying to update a volume it also display an error msg:

...

3ab47e19d21c4672973e57e7a8c85c83 - - -] Updating volume: 22f86318-5668-466e-b80a-9452314fa5f6 with {'status': 'error'} due to: No valid host was found.  error_out_volume /usr/lib/python2.7/dist-packages/cinder/volume/flows/common.py:87

...

On cinder-volume.log we can see that the driver is loaded successfully. Anyone had this kind of problems before? It's really painful since we already try to use the LIF mgmt port of the Vserver to connect and we are getting the same result, also I forgot to mention that every time that we make any change on the cinder.conf file, we restart all the services (api,scheduler and volume).

Also another strange thing is that we have running this cluster-mode array with the same settings on a Grizzly Cinder environment.

Thanks in advance,

German

Ah, I see a typo in your extra specs.

cinder type-key 3250direct1 set volume_backend=3250direct1

cinder type-key emc set volume_backend=iscsi_emc_vmax_1

should be

cinder type-key 3250direct1 set volume_backend_name=3250direct1

cinder type-key emc set volume_backend_name=iscsi_emc_vmax_1

These lines from cinder-scheduler.log denote that it tried to match the volume type against both backends, but failed:

How have you defined the volume type? As an admin, could you paste in a reply the output of executing the following CLI command:

cinder extra-specs-list

Hi how are you? Thanks a lot for the quick response. Sure, here's the output:

The name of your volume type is incorrect in your "cinder create" command. You had

cinder create --volume-type 3250direct1 --display-name test 1

but your volume type is named 'netapp3250'... try this

cinder create --volume-type netapp3250 --display-name test 1

Let me know if that is successful.

Oh sorry i forgot to update the first part of the question, we are using the correct parameter.

...

[3250direct1]

volume_backend_name=netapp3250

volume_driver=cinder.volume.drivers.netapp.common.NetAppDriver

netapp_server_hostname=xx.xx.xx.xx -> cluster mgmt ip addr

netapp_server_port=80

netapp_storage_protocol=iscsi

netapp_storage_family=ontap_cluster

netapp_login=admin    

netapp_password=xxxxxx

netapp_vserver=openstackVS1

But we are still receiving the same error message.

The volume type is defined incorrectly:

| b016ff8c-47de-4a1b-94d5-80a639d4871d | netapp3250 |   {u'volume_backend': u'3250direct1'}    |

The extra spec "volume_backend" should match the same line as in your cinder.conf file:

volume_backend_name=netapp3250

So you'll need to redefine the volume type with "cinder type-key b016ff8c-47de-4a1b-94d5-80a639d4871d set volume_backend=netapp3250"

After that the output should look like this:

| b016ff8c-47de-4a1b-94d5-80a639d4871d | netapp3250 |   {u'volume_backend': u'netapp3250'}    |

You can then do as Bob mentioned and create the volume with "cinder create --volume-type netapp3250 --display-name test 1"

If Andrew's latest suggestion still doesn't fix the problem, please paste in a full excerpt from the cinder-scheduler logs.

It didn't work, here's the complete process:

mysql drop cinder; mysql create cinder;

cinder-manage db sync


cinder type-create 3250direct1

cinder type-create emc

cinder type-key 3250direct1 set volume_backend=3250direct1

Ah, I see a typo in your extra specs.

cinder type-key 3250direct1 set volume_backend=3250direct1

cinder type-key emc set volume_backend=iscsi_emc_vmax_1

should be

cinder type-key 3250direct1 set volume_backend_name=3250direct1

cinder type-key emc set volume_backend_name=iscsi_emc_vmax_1

These lines from cinder-scheduler.log denote that it tried to match the volume type against both backends, but failed:
