[chef] Re: Having a problem with HA Chef

[Tetsu Soh < >]

Hello,

Interesting. I am setting up HA Chef too.

I think, the client keys for web UI should be different. But anything 
else, should be the same (on NFS).

I wonder is it possible to set up 2 chef server in active-active way.

Regards,
Tetsu
