Hello, I'm deploing a new email cluster using Dovecot over GFS2. Actually I'm using courier over GFS. Actually I'm testing Dovecot with these parameters: mmap_disable = yes mail_fsync = always mail_nfs_storage = yes mail_nfs_index = yes lock_method = fcntl Are they correct? RedHat GFS support mmap, so is it better to enable it or leave it disabled? The documentation suggest the use of flock. What about it?
