    Perhaps the management server serializes delete commands that it sends
    to a given
    plug-in.

>          Components: Management Server
>    Affects Versions: 4.6.0
>         Environment: All

> Note: Relates to managed storage only.
> Due to the fact that a volume does not enter the "Expunged" state until after a callback
method is invoked (which happens after the plug-in is notified to delete the volume in question),
the current getUsedBytes implementation (in SolidFirePrimaryDataStoreDriver) was assuming
the volume just deleted would not be included in the used-byte count calculation.
> The fact that the code does try to count this volume in the used-byte count calculation
leads to an exception being thrown and the removed column not being updated.
