[Linux-HA] Heatbeat/DRDB/MySQL & Heatbeat/Ldirectord Both Working

[Gary W. Smith]

Good to hear that it's working out well for you.  We have setup several
clusters using DRBD and MySQL.  We haven't, to this day, had any problem
with our clusters of any significance.  From our firewalls to our web
servers, we are using Linux-HA across the board.

We have several MySQL cluster slaving a MySQL cluster over the WAN
giving up very high availability (mostly reads) for a variety of
products we run.

I now have two clusters up, and both of them seem to be running well.
One cluster is a pair of HA load balancers directing traffic to a pair
of Java servers running multiple instances of tomcat. The tomcat
servers, in turn, query matching instances of MySQL running on a second
HA cluster (DRBD). Today I enjoyed doing my first power-plug test and
watching our MySQL-based client application keep ticking. I conducted
this test in front of an important visiting dignitary (my wife) and the
system performed as advertised. Woohoo! (I had already tested it a few
times with hb_standby, so I wasn't going completely on faith.)

I'm having so much fun I thought I'd share it with the list. :-)
