Hi @ll i have a question about feature Shared Writeable MMAP and its relation to concurent file use.
Background, over years i am hosting dovecot imap servers behind loadbalancers on a drbd master/master setup shared formated storage ocfs2 1.4.3 maildir without problems. the dovecot wiki says http://wiki2.dovecot.org/Director Director can be used by Dovecot's IMAP/POP3/LMTP proxy to keep a temporary user -> mail server mapping. As long as user has simultaneous connections, the user is always redirected to the same server. Each proxy server is running its own director process, and the directors are communicating the state to each others. Directors are mainly useful for setups where all of the mail storage is seen by all servers, such as with NFS or a cluster filesystem so the director service is most installed on the loadbalancers mainly with nfs storage, proved to be a "must have" after online investigation and long lasting reality tests , i guess "or a cluster filesystem " isnt true for ocfs2, cause on drbd it works fine with concurent files use ( i.e mailbox format maildir ) by feature Shared Writeable MMAP. Can sombody confirm this, or teach in easy words how it works ( or not ) and why ?
