Olivier Lemasle commented on CLOUDSTACK-6669:
---------------------------------------------
The previous patch enables the support of volume resize in
cloud_usage.usage_volume (resize events are correctly handled).
But VolumeUsageParser has not been updated, and usages are wrongly consolidated
in table cloud_usage.
Example with a data volume created as a "Custom Disk" with 1 GB, resized twice
(to 3 GB and 8 GB), and then assigned to an other disk offering with 20 GB.
All these steps are correctly recorded in usage_volume:
{noformat}
mysql> select * from usage_volume where id = 6;

| id | zone_id | account_id | domain_id | disk_offering_id | template_id | size

but consolidation shows the last state only for each period:
{noformat}

from cloud_usage where usage_id=6 and usage_type = 6;
+-------------------------------------------+-------------------+-------------+-------------+---------------------+---------------------+
