find /vservers/<name> -xdev ! -links 1 -printf "%s\n" \
| gawk '{ sum+=$1 } END { print sum }'
will give you an estimate of the number of 'shared' bytes,
where local hardlinks are accounted too ...
find /vservers/<name> -xdev -links 1 -printf "%s\n" \
| gawk '{ sum+=$1 } END { print sum }'
will sum up the non hardlinked (definitely not shared)
files in a vserver ...
still the ultimate tool to do this is missing ...
