Hello I've been keeping a list of configuration changes to setup Cyrus in an active-active two-node cluster (I'm using DRBD and OCFS2 for that). Here's the list of things I have so far: * Don't use BerkeleyDB (set all databases which default to berkeley to skiplist); * Under configdirectory, move the "log", "proc", "db" and "socket" directories to local storage and symlink (or mount -obind) them to avoid conflicts between the two cyrus instances; * Change the append_newstage() function in imap/append.c to add some host information to the "stage." file names, to avoid PID clashes between the two cluster nodes; Dave McMurtrie has also suggested me modifying the mmap() call in the map_refresh() function to use MAP_PRIVATE instead of MAP_SHARED for performance reasons. Is anyone aware of any side effects that this could cause? Any input on this list would be really appreciated. I think it's important to keep a list of things like this that people thinking about a similar setup can refer to (or give up on the idea :) Thanks, Andre ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
