Quota Clone Plugin

[MK]

Hello Everybody,

just a short question, maybe someone used this plugin and can give me a short answer.

I have configured dovecot Quota Clone Plugin to copy quota information into a MySQL Database.
Works finde, but dovecot writes the quota information only to the database if the quota is triggert by new email 
or something else like this. So I don't have all my user in the MySQL Database. 

Is there any command I can use that can trigger dovecot to write the quota information of all the users to the database 
one time, so that I have all my user quota information copied in the database? 
I have tried "doveadm quota recalc -A" but it took quite a long time and there is a very high I/O Load on the server, so I stopped it. 
I don't think this is what I want to do. Maybe there is another way. 

For all of you who don't know this plugin.
