[Dovecot] Dsync help, new attempt

[Torbjorn Astlind]

I observe that dsync fills Maildir correctly incl. cur, if I delete 
Maildir just before dsync runs.
Can the failed mbox to Maildir conversion be caused by dovecot creating 
Maildir automatically if a client connects to dovecot?
Should dovecot be shutdown when running dsync?
All the best,
Torbjörn

Hi all,
I have dovecot serving aprox 200 users through mbox, but the time has 
come to migrate to a new server, and to use Maildir.
Using rsync from the old server I get all user data, i.e  /home/*, and 
inboxes i.e /var/mail/* to a new server. This has worked well for some 
time as backup.
The dsync should convert everything to Maildir, and it does... to an 
extent.  (linebrakes for easy viewing)
What I see, is that often, the /home/mail/xxx is NOT resulting in 
/home/xxx/Maildir/cur
All mailboxes from /home/xxx, are properly converted to 
/home/xxx/Maildir/.name_of_ box
Am I misunderstanding something?
I get it to work sometimes if I delete the ~/Maildir completely before 
doing the dsync.
All, and any help most welcome,
Torbj?rn





for i in `cat /home2/torbjorn/SCRIPTS/userlist.txt`;
do dsync  -D -v -f  -u $i  -c /etc/dovecot/alt_config/10-mail.MBOX.conf 
  backup maildir:~/Maildir;
done > /home2/torbjorn/SCRIPTS/mb2mdRES.txt 2>&1

the  -c 10.mail.MBOX.conf contains, the parts I think are relevant for 
the dsync operation:
mail_location = mbox:~/home:INBOX=/home/mail/%u
namespace {
         type = private
        separator = '/'
       inbox = yes
}

dsync(root): Debug: Namespace : type=private, prefix=, sep=/, inbox=yes,
