[Spacewalk-list] Replicate spacewalk core to another data center for HA

[Musayev, Ilya]

Paul,

I'm going to disappoint you a bit here, satellite-sync does not sync clients/systems.

Man page only mentions:
Channels
Rpms
Packages
Errata
Kickstart



Hence I figured I may as well setup slony with rsync or extend the satsync library to include systems - I'm under assumption it was left out on purpose.

Regards
ilya

well I have a different plan which I'm going to test in the next week or so

As far as i know satellite-sync should work between instances of spacewalk so if i combine that with a squid 3 revers proxy (possibly with an ssl bump configured ) or an LVS based load balancer and finally add in a few bind 9 tricks to do location based responses. I think I should be able to do this using stock tools without too much difficulty.

Ill let you know how it goes
