The MySQL stuff is what interests me. I need to get up to speed with  
DRBD and MYSQL so I was hoping to mess around with something this  
week. I can imagine the clutter of cables and machines !!! I can not  
wait !

But before I begin I thought I would see what you guys were up to.  
Anyone doing any MySQL High Availabilty stuff ? Any replication for  
Read scaling or the like ?

The DRBD stuff shows promise for filling in some of the holes that  
other MySQL solutions have.
