Anyone know how to setup dovecot with mdbox so that it can be used through shared storage from multiple hosts? I've setup a gluster volume and am sharing it between 2 test clients. I'm using postfix/dovecot LDA for delivery and I'm using postal to send mail between 40 users. In doing this, I'm seeing these errors in the logs
Dovecot assumes that the filesystem behaves the same way as regular local filesystems.

Looks like gluster doesn't fit that assumption. So, the solution is the same as with NFS: http://wiki2.dovecot.org/Director
