[Sasikanth Eda]

Hi,

when configured in multi-back mode using ibmnas driver, cinder service throws below error;

This is caused due to missing of appending the nas options (self.configuration.append_config_values(nas_opts))

Sasikanth,

Are you working on a fix for this?

[OpenStack Infra (hudson-openstack)]

Fix proposed to branch: master
Review: https://review.openstack.org/83425

[Jay Bryant (jsbryant)]

Making this a high priority as it should be a small fix but notable impact. Would be good to get this fixed in Icehouse.

[Mike Perez (thingee)]

We'll see if we end up with another RC, otherwise backport.

    Append nas_opts to IBMNAS_NFSDriver configuration

    'nas_opts' were added in the NFS Driver (nfs.py), but were not appended
    to the IBMNAS driver configuration, causing failure with the multi-backend
    configuration of driver.

    Adding the missing configuration.
