Hi All,

If I set *max_attempts = 1* in /etc/cinder/cinder.conf, then the volume
creation via 3rd party driver is success.
However, this setting does not work for volume deletion.

The volume gets deleted at openstack but never executes the driver code.

I did above changes based on the error stack trace.
*/opt/stack/cinder/cinder/scheduler/filter_scheduler.py
-> _populate_retry*

However, i  am not sure if this is a bug or an issue of missing
configuration.


Regards,
Amit
