In our experience. A ring with more of 4 servers is bad, we have sync problems everyone. Using 4 or less works perfect.

As someone who is about to begin the process of moving from maildir

mdbox on NFS (and therefore just about to start the 'director-ization' of everything) for ~6.5m mailboxes, I'm curious if anyone can share any experiences with it. The list is surprisingly quiet about this subject, and articles on google are mainly just about setting director up. I've yet to stumble across an article about someone's experiences with it.
- How big of a director cluster do you use? I'm going to have millions of mailboxes behind 10 directors.
I wouldn't use more than 10.
Cool
Interesting. That's good feedback. One of the things I wondered about is whether it'd be better to deploy a 10-node ring or split it into 2x 5-node rings. Sounds like splitting it up might not be a bad idea. How often would you see those sync problems (and were they the same errors as I posted or something else)? And were you running poolmon from every node when you were seeing sync errors?
