IMAPD Missing quota root

[James B. Byrne]

We have a problem with quota settings on a new v3.0.5 service. The
mailboxes were transferred via rsync from oldserver:/var/spool/imap/
to newserver:/var/spool/imap

The mailboxes.db was unloaded on the old server using mboxelist,
transferred to the new server, and then loaded into an empty
mailboxes.db.

We ran 'reconstruct -f -r -G -V max user/*'.  All this when well. 
However, we cannot re-establish a quota root for the transferred
mailboxes.  When we try to run quota from the command line then we see
this:

sudo -u cyrus /usr/local/cyrus/sbin/quota -f user/*
   Quota   % Used     Used             Resource Root

If we just run it to get a list of the user quotas then we the same
thing:

sudo -u cyrus /usr/local/cyrus/sbin/quota
   Quota   % Used     Used             Resource Root

And if we run it to rebuild the quotas for a specific user then we
first see this:

# sudo -u cyrus /usr/local/cyrus/sbin/quota -f user.x
user.x: quota root user.x --> (none)
user.x.Bayshore_Hobbies: quota root user.x --> (none)
user.x.Drafts: quota root user.x --> (none)
user.x.HLL: quota root user.x --> (none)
.  .  .

But if we rerun the same command after seeing the above then we this
instead:

# sudo -u cyrus /usr/local/cyrus/sbin/quota -f user.x
   Quota   % Used     Used             Resource Root

In maillog we see things like this:

May 22 12:03:43 inet17 CYRUS/lmtpunix[85335]: LOSTQUOTA: unable to
record change of 1639 bytes and 1 messages in quota user.x: Quota root

and this:

user.y.Sent
May 22 04:14:00 inet17 CYRUS/ipurge[68591]: LOSTQUOTA: unable to

record change of -22899753 bytes and -252 messages in quota user.x:

On the old (v2.3) service we have no such problems.

How do I transfer quotas?  How do I create the missing quota roots?
