That's a lot of mail (likely a large user base--not given), on a
filesystem not designed for such, on a decent SAN controller--LUN RAID
configuration not given.

The problem is: You're running in problems with shared folders. You can't
read your neighbors storage-engine from ldap.
Yes, but I didn't have any shared folders, so it worked. Your milage may
vary, as I said... :)

Hi All,

It would be MUCH easier if Dovecot could read maildir: or mdbox: from LDAP

Actually this works :-) Our userdb looks similar to:

I thought of a per-user migration, that way I don't need extra space.

I never tried it, but it should be possible to provide the mail_location
from the user repsoitory (LDAP, SQL, whatever)
So you can keep your global config, and
Will dsync also use zlib-compression when copying mails from one side to
another?
Wouldn't this be a good way to compress existing mails?
http://wiki2.dovecot.org/Plugins/Zlib
says, there's no way to do that. But dsync should respect the zlib-Plugin...

If you have double diskspace:
Just use "dsync mirror" in the background to prepare the change. After that
it's just a short downtime to migrate incrementa
Other important thing to consider is message expunging. With mdbox
you are "delaying" the I/O associated with deleting e-mails. We have a
nightly cronjob that expunge messages from mdboxes.
If you have en EVA (wich one? 4.400? 6.400? ) you also can consider

I always wanted to make some mesurements about several influences to the

Sorry, doesn't work in v2.0 and I don't think it's possible to fix it without

works there.
Hello,

In this example user001 is sharing two foders named "docs-abc" and "docs-a.b.c"
