Hello Everyone,
These Patches add support for continious replication to colo. This means
that after the Primary fails and the Secondary did a failover, the Secondary
can then become Primary and resume replication to a new Secondary.
On a side note, I wrote a Pacemaker Resource Agent for colo which I will
post when its ready.
I have to say it's quite fun to randomly kill a Node, wait for resync
and repeat and see how the VM stays alive all the time. :)
Regards,
Lukas Straub
