If your log file is not big, please inline it so that we can easily
comment on it.
The 'Used' field means the size of used data objects that are not
shared with any other vdis. On the other hand, the 'Shared' field
means the size of used data objects that are shared with other ones.
In your case, most of data objects are shared with the snapshot, so
the number in the 'Used' filed is small.
