<p>I need to move from one mount point to multiple mount points and
I'm searching for the best strategy.</p>
<p>Right now my take is to script a rsync of the folders that need
moving, change dovecot config and restart. <br>
</p>
<p>In order to do this I need to know in advance what users will end
up on the newly added mount point.</p>
<p>Thank you for 'doveadm user'. This seems to be the appropriate
tool.</p>

<div dir="ltr">Dovecot knows where the user's home is, you don't
need to guess. With mail_home or with Passdb variables you can
define the user's home location and you can use 'doveadm user'
to show where the home directory is in the filesystem.</div>

<div>However, if you are migrating I would use dovecot sync or
similar tool instead of doing the manual process. <br>

<div>Hi Adrian,</div>
<div><br>
</div>
<div>It depends much on your site configuration. <br>
</div>
<div><br>
</div>
<div>In our case, we have several mount points and we
distribute our user mailboxes using username hash
(%N)[1] and limit this hash to the number of mount
points. We preferred %N over %H because the
distribution of users was much better.</div>

<div>Ex. xstore%2.3Nn turns to xstore00, xstore01 and
xstore03.<br>

<br>
I want to ask if any of you has done a migration
from a single storage <br>
to multiple back-end storages and what is the best
strategy for folder <br>
hashing that you use.<br>
<br>
Using something like %H or %M how do you predict
where the mail will end <br>
up in order to move the existing folders ?<br>
<br>
Thank you !<br>
