Hello, This is my first go at setting up any HA services, so I wanted to see if anyone on the list had a similar setup or any recommendations on doing this better using drbd. I'm setting up 2 servers with 2 application services on them. One application service is postgresql database (about 5GB of data in database). The other is custom software that does a lot of file-based I/O (about 15GB of files) with a custom TCP server in front of it. My idea is to have one server being the master for the custom software and the other being the master for the postgresql database. The other server will be a stand by for the other service. Both will run run ubuntu 10.04 LTS and be connected by 2 cat6 1Gb cables. This will hopefully distribute the load, as I am worried about the postgresql clobbering the custom software (which requires very high responsiveness). So is setting up 2 brbd's in opposite configurations on 2 hosts a good idea? I'm mostly worried about performance and the headache of admin if the links go down. 2 cases of split brain on 2 boxes doesn't sound fun at all. Thanks! J
