Old topic. Exuse me for opening it again.
Being virtualized or being installed on not ext3 partition, Zimbra do not show Total disk space usage graphic of Zimbra partitions.
For example, for openvz we use simfs as a file system.
Here is the patch for simfs.
Code:
root@localhost:/opt/zimbra/libexec# diff -u zmdisklog.orig zmdisklog
--- zmdisklog.orig 2008-10-24 13:02:35.000000000 +0700

} Nothings changed with new release

It could easily be modified to suit partitions rather then EXT3
