Thank you for using OpenVZ, we're happy to hear it. :)

There is no such limit. Actually I don't quite understand your phrase
"progressively increase its (filesystems) size (with rsync for
example)". Do you mean that you just add files to this filesystem and
consequently the amount of busy blocks is increasing?
The most common reason of the error: "vzquota : (error) Quota on syscall
for 123: Device or resource busy" is the presence of Linux disk quota on
the filesystem where vzquota is trying to start. Check it, please. 

Thank you,
