Disk quota problem

I have such problem. I installed system on a single hard drive. After that I have added a new hard drive and mounted it on /home1. I have enabled quota in webmin on this new HDD (User and group quotas active). Then I run Re-Check Configuration in virtualmin, it says “Both user and group quotas are enabled for home and email directories.” I created new virtual server “domain.com”, the folder /home/domain was created. I moved this folder to /home1/domain and created a symlink (/home/domain => /home1/domain).
User “domain” quota status in webmin is “Used 1.12 GB”, but in virtualmin it is such:
Allowed disk quota 5 GB;
Disk space used 460 kB;
Size of databases 408 kB;
Percent of quota used 0%.

How can I resolve this problem? Disk space used in virtualmin must by at least 1.12 GB.
Many thanks!
