Quick failover to a sycnhronous cold stand-by, and a warm slave that will let you do large table operations without much in the way of downtime. Hi Eric,

The shared disk in this case is drbd. DRBD is a fine product for replicating block devices of single disk systems. It’s made redundant by raid and doesn’t provide as much protection as binary log failover. You can find my notes on why I don’t recomment DRBD for MySQL in drbd in the real world.

I have a postgresql D.B running with 900 T.P.S , and so far so good, I've been able to go back and forth between the two, and all my data have been replicated properly. We have not experience any lost in our T.P.S compare when we were not using DRDB. I think we will continue playing around with it before we decide to go live.

The binary log replicated slave uses about 50K/s net read. The DRBD slave at the same time uses 1800K/s net read. Mark,
