LVS-DR director connecting to itself...

[Helgi Hrafn Gunnarsson]

Hi.

I need a client on the director because the web server that uses the database is hosted on V3, and V3 is also the director. Thus I presumable need V3 to connect to V3.

I'm not sure we're understanding each other here. It's so obvious to me why I need V3 to connect to V3 that your last question frankly confuses me. What would you suggest other than connecting to the VIP from V3, when I need V3 to talk to the databases through LVS?

Kind regards,
Helgi Hrafn Gunnarsson
