[Spacewalk-list] Clustering Spacewalk.

[Bernard McCormack]

Maybe I'm asking the wrong question but I have two data centers and I
don't want all my host to have access over the site to site vpn. What
would be the best configuration for this be a spacewalk proxy? or
would it be a redundant spacewalk server in the second site? We want
to be able to centrally track all of our servers on spacewalk and if
possible not worry about the primary site going down.

It wasn’t smart enough to “reconnect”. I didn’t give it much effort to debug. However that was before the use of SCAN listeners in our environment. I bet leveraging the SCAN LISTENER layer spacewalk would work just fine as a whole.
