##### SUMMARY
<!-- Explain the problem/feature briefly -->
physical volume size reported is wrong, and doesn't change after you write a lot of data to the VM's root disk (be it linked clone or full clone)
##### STEPS TO REPRODUCE
configure "volume.stats.interval" to 60000 (these are milliseconds, not seconds as stated atm - I raised a separate PR for this).
1. Grep management-server.log for "GetVolumeStatsCommand" and observe it's running each minute
2. Inside the VM, write i.e. 50MB to disk - "dd=/dev/urandom of=ddfile bs=1M count=50; sync"
3. Wait for next run of GetVolumeStatsCommand from the mgmt logs - check the size reported in the text output and also on the GUI

##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
Correct physical size is reported
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
0.53KB reported instead of the real size (linked clone - from image bellow is ~ 220MB)
