Re: [Dovecot] Problems using GFS2 and clustered dovecot
Sorry, it's just struck me that I've missed out the most important information- I am using maildir++. Sorry :-(. The index files are kept on the shared volume. And to answer the other question again, mmap is off.

I am trying to use dovecot. I've got a GFS2 shared volume on two servers with dovecot running on both. On one server at a time, it works.
The test I am trying is to attach two mail programs (MUA) via IMAPS (Thunderbird and Evolution as it happens). I've attached one mail program to each IMAPS server. I am trying to move emails around in one program (from folder to folder), and then checking it on the other program. I'm testing in effect how it would work if my users log on twice and end up on different servers.
I seem to suffer from never ending index file corruption:
Where are index files located ?

This happens pretty quickly. I can also get message duplication- if I move a message from one server to another, I can get a message in the original folder and the destination folder.
I am using RC28. I have tried using fcntl locking and dotlocking with equal lack of success.
Can anyone offer any advice?
