+++ This bug was initially created as a clone of Bug #667360 +++

A user reports a problem with the quotas reported over NFS for a user who has been allocated 5Tb of quota. The quota for that user is reported as being only 650G instead of the actual 5Tb.

On the client client:

Filesystem blocks quota limit grace files quota limit grace
nfs:/export/work 696848372* 200000000 0 179days 73350427 0 0

On the server:

Disk quotas for user user1 (uid 123):
Filesystem blocks quota limit grace files quota limit grace
/dev/sdc 4991815668* 200000000 0 179days 73350427 0 0 

This problem is similar to the problem reported on the centos bug tracker
http://bugs.centos.org/bug_view_advanced_page.php?bug_id=4071
which also contains a patch for this issue.

The patch does not fix it. It just divides limits by 2^20 on transmission from rpc.rquotad making mangled values on client site. It would break compatibility between patched and unpatched servers and clients.
