[I] Volume resize usage event may record incorrect size in cloud_usage [cloudstack]
Yuliia7-1 opened a new issue, #13555:
URL: https://github.com/apache/cloudstack/issues/13555
### problem
When a volume is resized, CloudStack publishes a EVENT_VOLUME_RESIZE usage event that is later used for billing calculations and stored in cloud_usage.
In VolumeApiServiceImpl.orchestrateResizeVolume(), the volume size is updated before the usage event is published:
```
if (currentSize == volume.getSize() && currentSize != newSize) {
volume.setSize(newSize);
} else if (volume.getSize() != newSize) {
newSize = volume.getSize();
}
_volsDao.update(volume.getId(), volume);
```
The usage event is then published using:
```
UsageEventUtils.publishUsageEvent(
EventTypes.EVENT_VOLUME_RESIZE,
volume.getAccountId(),
volume.getDataCenterId(),
volume.getId(),
volume.getName(),
volume.getDiskOfferingId(),
volume.getTemplateId(),
volume.getSize(),
Volume.class.getName(),
volume.getUuid()
);
```
**Observed Behaviour**
The resize event uses `volume.getSize()` instead of the final resize target value (newSize).
In environments where billing is calculated from cloud_usage, we have observed discrepancies between:
the current volume size reported by CloudStack APIs/UI, and the size stored in cloud_usage following resize operations.
As a result, billing records may not accurately reflect the expected volume size history after one or more resize operations.
### versions
4.19.1
### The steps to reproduce the bug
1.
2.
3.
...
### What to do about it?
The resize usage event should be published using the actual final resized value (newSize) that was determined during the resize workflow.
For example:
```
UsageEventUtils.publishUsageEvent(
EventTypes.EVENT_VOLUME_RESIZE,
volume.getAccountId(),
volume.getDataCenterId(),
volume.getId(),
volume.getName(),
volume.getDiskOfferingId(),
volume.getTemplateId(),
newSize,
Volume.class.getName(),
volume.getUuid()
);
```
This would ensure that usage records and billing calculations are based on the intended resize value.
Affected Code: `server/src/main/java/com/cloud/storage/VolumeApiServiceImpl.java`
Method: `orchestrateResizeVolume(...)`

sounds like a bug to me

this description would indicate it works as expected, but I think the update is not happening before the event publishing.

Hi @Yuliia7-1 @DaanHoogland it seems like this fix could solve this issue? https://github.com/apache/cloudstack/pull/9459 (already present on 4.19.2)
