Hello,

Has anyone used Mac OS X for a real server in LVS/DR ?

Yes, I gave a presentation about a year ago and I remember that one of the attendees had a new shiny G4 with Mac OS X. It worked flawlessly.


Is it OK to use the loopback interface ?

You can but you don't have to.

sudo ifconfig lo0 inet 10.0.0.80 netmask 255.255.0.0

I can't get lo0:1 to work?

OS X is BSDish, so you need to use BSDish syntax:

ifconfig lo0 alias VIP netmask 255.255.255.255 -arp up

Also from an old post I heard that :
ifconfig lo0:1 inet 192.168.1.1 broadcast 192.168.1.255 netmask
255.255.255.0

will work on Solaris..

Yes, but you should use a /32 netmask for the VIP. Also I found an entry about setting up the loopback in the Howto (although I still disagree that this is the preferred and only working way):

Hey Joe, I couldn't find my list of RS OS I once made.
