ACTUAL RESULTS

Job fails due to incorrect power state

2019-12-07 10:18:47,324 ERROR [c.c.s.VolumeApiServiceImpl] (API-Job-Executor-25:ctx-40931858 job-91715 ctx-f6746e26) (logid:cfce0759)  For ROOT volume resize VM should be in Power Off state.

In cloudstack 4.9.3 there is no issue with scaleVirtualMachine.
also an alternate way to scale down a VM is using changeServiceForVirtualMachine api call and it will end up without job failing because it checks VM state by calling getState() function instead of getPowerState().
in addition this bug has been appeared after this commit:
https://github.com/apache/cloudstack/blame/4.13.0.0/server/src/main/java/com/cloud/storage/VolumeApiServiceImpl.java#L1081

calling changeServiceForVirtualMachine works as it should be:

@meysamfarazmand I think this was fixed in 4.14 can you check?
