Re: Cyrus - GFS slow start and poor performace

If you wish to do load balancing,

I suggest looking at nginx.

For documentation ... http://wiki.codemongers.com/Main

I don't have a lot of experience with GFS1 or OCFS, however I don't expect great performance.  I would imagine worse then ext3 or about the same is the best you will be able to achieve.

You may have better luck with syncclient, or setting up Murder with 2 Front ends and 1 backend.  I guess the bottom line is read-write configuration shared between 2 servers is .. (to me) hit and miss.  It really depends on what your trying to do with it, and how your trying to make it work.

In this case, I would not personally suggest a read-write with DRBD or ocfs/gfs as you are going to either encounter bugs from filesystems, cyrus, or both; if someone has a configuration where any 3 of those I just mentioned works great... then by all means please chime in.

I'm taking a look at the configuration of the mupdate replicated architecture.

As stated in an old post on this list (20-Dec-2005), the Cyrus 2.3 replicated
configuration seams a very good solution, but in the current documentation is
stated :"Note that load balancing is not possible with the current
replication code, but it is intended to be supported in the future."

I would like to use both server in active/active configuration, is it possible
with the mupdate replication?
Otherwise I will study the solution proposed by Bron to sync a local
mailbox.db with the GFS...but I have to pay attention on the contemporary of
the sync from the two servers.
