[Dovecot] Migrate from mlbox to maildir, lock problem
Hi
We've been using dovecot successufly for few month.
Previous setup : solaris 8, postfix+LDA, mbox + index on NFS (Netapp),
2500 accounts
Everything shared overs NFS, multiple servers connect to index, mbox.
mail_location
mbox:/var/mail/mbox/%u:INBOX=/var/mail/%u:INDEX=/var/mail/indexes_dovecot/%u
We had at first some issue with mbox locking, using lock_method dotlock solve
the issue.
The problem seemed to be with fcntl.
I Migrate to maildir to ease administration to use maildir quota
I use mb2md-3.20.pl to migrate the mbox everything works smooth.
Actual setup : solaris 8, postfix+LDA, maildir + index + control on NFS (Netapp)
I change the mail_location settings to
mail_location
maildir:/var/mail/maildir/%u:INDEX=/var/mail/indexes_dovecot/%u:CONTROL=/var/mail/dovecot_control/%u
And now I'm facing new locking issue :
Errors on user loging, users leaving mail on server downloading the
same mail over and over.
Numerous entries in log files :
May 2 11:19:03 gregorie dovecot: [ID 107833 mail.error] POP3(carini):
Maildir /var/mail/maildir/carini sync: UID inserted in the middle of

nformation. [2007-05-02 11:19:01]
Seems to be locking issue, numerous .nfs files in INDEX & CONTROL location
The maildirsize & dovecot-uidlist files aren't update properly
Does the patch posted here still apply ?
